TAM Potato 

(Engineering) An undefined blob resembling a potato, drawn in a free-body diagram to represent a body with some known and some unknown quantities. This is especially prevalent in TAM (Theoretical and Applied Mechanics) courses.

I didn't even bother drawing a car for problem #6 last night -- I just drew a TAM potato on wheels!

tamponator 

A person who inserts a tampon into what ever orifice they can eagerly find on another person; with or without the consent of that other person.

If you ever come in contact with a tamponator be sure to close your legs and mouth, at least.
