When a person climbs into the ceiling of a bathroom and cuts a hole above the shower recess for their erect penis to hang through and then ejaculates on the next unsuspecting user of the shower.
He was mortified to find his roommate had once again given him a Bomber's Surprise Shower when entering the shower to prepare for work. It would take him hours to remove all the semen from his hair.

When you get your significant other pregnant on Valentine's Day without them realizing, (or vise versa getting pregnant without them knowing)
It's a sick prank, but hopefully 9 months later it won't be so bad!

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!
