Actually masturbating. Only to be used when the person is actually masturbating (hence a/m). Kind of like 'mol' (masturbating out loud), but people use 'mol' when they are not masturbating.

M&M, a chocolate candy covered in a hard layer of an artificial color. Can come with a peanut center, or a simple chocolate center.
M&Ms are my favorite candy treat, they're great on ice cream!
