A sidepot is a girlfriend that knows you are cheating on her but still stays with you. The only reason that you even talk to her is for the gifts that she gives you and the sex. The average sidepot knows her place but on occasion a sidepot will try to talk back to you and threaten to leave you. When this happens you must put them back in their place. The ideal sidepot is at home while you are in college hooking up with a different girl each night.
Damn that chick is a sidepot.
