A sex act in which one partner sneaks into the other's room and gives them a blowjob while they sleep, usually waking them. (The recipient mustask for/consent to this in advance)
I was sound asleep when all of a sudden I was woken with a sneakybeej.
The action of sneaking up behind an unsuspecting individual and then inserting one hand between that person's knees and then slapping the insides of their legs while traveling upwards, mimicking a salmon swimming upstream.
Hey bro, can you video this dudes face while I dish him up a sneaky salmon.
