an erection that comes for no reason. it just happens. you could be in the locker room with a bunch of dudes. dont worry if it happens there. as long as it only happens once youre probably not gay, just unlucky.
its a quiet day in penisville. some young sperm cells have crawled into the penis and are playing in the veins.
Cell 1: Hey, whats that sound?
Cell 2: surprise boner!
Cell 1: The blood wasnt supposed to come till we see the hot chick on the bus!
Cell 3: DIVE!
Kid in real life standing in front of class: Oh God, not now!

When you surprise your girl with your boner and expect sex. And is met with partial success that ends with her unsatisfied. Could be worse.
Female: I really wish my boyfriend would seduce me, but all I get is boner surprise.
Male: I wanna have sex tonight. strategy? boner surprise!
Bro 1: bro! I was hanging with this new girl and she totally fell for boner surprise!
Bro 2: HA! Bro thatโs so classic!! (High fives)
