when you get cum in your belly button
Dude, I was jacking off and I filled up my salt lake.
Refers to the procedure by which a sizable puddle of ejaculate is deposited in the small of a female's back. Care must be taken in the process so as not to let your "ropes" create a sticky web instead of a consolidated pool. The desired effect is most readily accomplished following standard doggy-style intercourse. See also great salt lake.
So I was playing hide the flesh torpedo with Cindy last night and I totally sold out and laid a salt lake on her tramp stamp.
