Dirty Surprise 

While getting a blowjob, dump in your hand, then ejaculate in her mouth while slapping her in the face with your feces.

Can i give you a Dirty Surprise? I give my dog one every Wednesday.

Ralph's Dirty Surprise 

While receiving oral sex, a male partner stimulates the other partner's uvula resulting in the partner giving oral sex to vomit on the male partner's erect penis. The male partner then inserts his soiled penis into the other partner's rectum using the vomit as anal lubrication.

I gave Sherry 'Ralph's Dirty Surprise' last night.

Dirty Sock Surprise 

Same as a normal sock surprise, however, it is done with a used sock and going commando. The resulting odor can be used as either an aphrodisiac or as a way to disorientate your new friend.

guy 1: Did you pull off that sock surprise last night?
guy 2: You bet!...but I did a dirty sock surprise. As soon as I pulled that magic out and she caught a whiff, it was as if candles lit the room and kenny g played played a single breath solo...she didn't care about the size of my penis anymore, love was in the air!
