fatitude (they go around the Earth like belts on a fat person)
laddertude (like rungs on a ladder going up)

Any location on Earth is described by two numbers--its latitude and its longitude. If a pilot or a ship's captain wants to specify position on a map, these are the "coordinates" they would use.
Actually, these are two angles, measured in degrees, "minutes of arc" and "seconds of arc." These are denoted by the symbols ( °, ', " ) e.g. 35° 43' 9" means an angle of 35 degrees, 43 minutes and 9 seconds (do not confuse this with the notation (', ") for feet and inches!). A degree contains 60 minutes of arc and a minute contains 60 seconds of arc--and you may omit the words "of arc" where the context makes it absolutely clear that these are not units of time.
Calculations often represent angles by small letters of the Greek alphabet, and that way latitude will be represented by λ (lambda, Greek L), and longitude by Ï (phi, Greek F). Here is how they are defined.
Imagine the Earth was a transparent sphere (actually the shape is slightly oval; because of the Earth's rotation, its equator bulges out a little). Through the transparent Earth (drawing) we can see its equatorial plane, and its middle the point is O, the center of the Earth.
To specify the latitude of some point P on the surface, draw the radius OP to that point. Then the elevation angle of that point above the equator is its latitude λ--northern latitude if north of the equator, southern (or negative) latitude if south of it.

On the globe, lines of constant longitude ("meridians") extend from pole to pole, like the segment boundaries on a peeled orange. Every meridian must cross the equator. Since the equator is a circle, we can divide it--like any circle--into 360 degrees, and the longitude Ï of a point is then the marked value of that division where its meridian meets the equator. What that value is depends of course on where we begin to count--on where zero longitude is. For historical reasons, the meridian passing the old Royal Astronomical Observatory in Greenwich, England, is the one chosen as zero longitude. Located at the eastern edge of London, the British capital, the observatory is now a public museum and a brass band stretching across its yard marks the "prime meridian." Tourists often get photographed as they straddle it--one foot in the eastern hemisphere of the Earth, the other in the western hemisphere.
A lines of longitude is also called a meridian, derived from the Latin, from meri, a variation of "medius" which denotes "middle", and diem, meaning "day." The word once meant "noon", and times of the day before noon were known as "ante meridian", while times after it were "post meridian." Today's abbreviations a.m. and p.m. come from these terms, and the Sun at noon was said to be "passing meridian". All points on the same line of longitude experienced noon (and any other hour) at the same time and were therefore said to be on the same "meridian line", which became "meridian" for short.

All longitude lines are long, since they all go from the North Pole to the South Pole. Some latitude lines, such as those at 80 degrees North, are shorter than others, such as the Equator--they are not all equally long. This distinction makes it easy to remember which type gets the name "longitude."

Latitude lines run east and west and are parallel across the earth's surface so think of them as the rungs of a ladder (as in "ladder"-tude).
Think of lines of longitude that stretch from the North Pole to the South Pole as "long."

longitude means the distance measured in degrees east or west of zero degree
WHERE AS LATITUDE
A DISTANCE MEASURED IN DEGREES NORTH OR SOUTH OF EQUATOR,
THE WAY TO REMEMBER IS THAT LONGITUDE
THINK OF LENGTH FOR LONGITUDE.
THE OTHER ONE IS JUST OPPOSITE TO IT.

Latitude has an ATTITUDE that goes back and forth, east and west.
Longitude has a LONG line from the north pole to the south pole.

Think it´s a long way to the north pole.. and you have to go up for that. so up and down is longitude.

longitude are the LONG lines that go up and down.

think JC on the cross. He is longer up and down than he is across. so the longitude is the up and down. his shoulders are his LATS ( if you know bodybuilder talk)
