Like if you stired water real fast would it create friction on the sides of the container it was being stired in and heat up.

Yes, in one of Joule's (the person the unit is named after) experiments, he heated water to boiling with only stirring.

Absolutely. The only thing that cannot get heated up is something that its coefficient of friction is zero. Water has a coeffecient of friction and therefore any way that the molecules get in contact with one another then heat will be generated. The difference is that water will not retain the heat hence loosing it faster than you can reliably measure.

Water heats from merely flowing because there is friction from its own molecules; it also heats when its mechanically aggitated because of the friction it creates. In short all ;friction is the transformation of movement into heat energy ;all friction creates heat.

yes, you've got it. Remember "heat" in this example is just the motion of molecules.
