1.
When a female (or male) gives a male a hand job using an excess amount of lotion or lube. Usually administered when one is too lazy to perform sex or oral sex. Term is used due to the "slipping" and "slapping" sounds made when ones hand is vigorously working the lotion/lube covered penis.
I gave Chris a slip slap this morning because I was too tired to give him head.
