IT MEANS THAT YOU WILL BE PURCHASING A NEW OR REBUILT ENGINE.
THE ROD THAT IS CONNECTED TO THE PISTON IS GOING TO FLY OUT AND GO THROUGH THE ENGINE ASSEMBLY.

Normally this refers to having bad bearings on crank and connecting rods! There are exceptions, - but they are few! I have seen rods that broke, and wristpins (in piston "connection" to rod) that have let go, but they are pretty rare!
Usually the bearings on crankshaft get so worn that they no longer hold oil pressure, this is turn "starves" the bearings, damages the crank, and eventeually the rods may "let go"!
Of course this can happen if you are a "high rev." nut, -- if it turns fast enough and long enough,--something is going to "let go" and parts will fly! Problem is aggrivated if you do this as soon as engine starts, and oil is thick, and not full oil pressure built up in engine yet!
Of course this can be worn out bearings, - as after a couple hundred thousand, - if you haven't kept oil changed on regular schedule! too!
(6:45 PM) Whoa! These descriptions are getting way out of hand! it is possible that all you need to do is have a mechanic pull off the oil pan and put in new inserts, - If caught soon enough it is just "loose bearings" yet! Once they get this way, no amount of oil will solve the problem, (so forget that "cure")-- if it is already full now!
If you are just starting to get a light "knocking" sound when accelerating or decelerating, it might be the "thrust bearing on crankshaft, - (not rod bearings) Although rod bearings make somewhat the same sound. A "good mechanic" can tell you pretty much what it is and how bad it is. Biggest indicator is how oil pressure holds up when hot! If the light conmes on (only occasionally) or the oil pressure (reading a gauge) is prety low, but doesn't seem to go away completely when it is hot, The crank may not be damaged yet!
Also you can have a "bottom overhaul", - by removing the engine and taking the crank out and having it re-ground, - or replace it with one that is new- or re-ground, -- without rebuilding the entire engine! A mechanic that is any good can probably do that for you from 6-8 hundred, (which is a lot cheaper than a rebuild),- instead of $1,700 - up!- Of course if the car is old enough, you might consider a used engine that still runs good, - may cost you just a little more than "bottom overhaul" on the one you have!
Bought a engine for wife's Plymouth Acclaim for $200 (from a wreck),- and changed it out myself in a weekend! It "dropped" a valve seat, and ruined the head, Would have cost me about $350 to put a new head on, so that was the cheapest route! Just bear in mind that I am the mechanic , - so my labor is "free!"

Usually it's low on oil; when a rod bearing wipes out, it says BAK-BAK-BAK. if you want to know for sure, take off and put back one plug wire at a time. If you get to one where the noise stops, that's the bad bearing. If you run it more, it wipes out the whole crank end of the connecting rod. If you still don't get the picture, the lower con rod breaks in half, and it's liable to break out the side of the block. If you are traveling fast enough and really think you can make it, the whole episode becomes an amusing anecdote to be told at the bar.

The short answer: stop running it, if it even still runs. I'm guessing that the motor makes some nasty noises that are probably caused by blown bearings. If so, it's more likely that the motor seizes, but on occasion, a connecting rod can break and actually break through the side of the engine block.

It means that the rods located in the block come free and shoot through the block.
This is caused when an engine has excessive wear or low on oil.
It is also usually refereed to as throwing a rod not slinging.

When a connecting rod (what connects the piston to the crankshaft) has a bearing cap come loose or it breaks in half, it comes loose from the crank. As the crank is rotating it will hit the loose end of the rod and smash it right through the side of the engine block. Instant destruction!

It means your engine is gone! Did you already sling a rod? You might be able to rebuild it.

It means, turn your car off, open the hood, wait approximately 30-45 mins, stand in front of the car facing the hood and while bending forward as far as possible, place your lips directly on the engine block and kiss it goodbye!

that means that your motors con rod is going to fly off and create a crack or hole in your block

connecting rod? or push rod?
