Occurs when an unexpected guest knocks on your bedroom door when you are masturbating and about to orgasm, and you open the door and ejaculate on them, shouting "Surprise Party!" Common in college dormitories.
I knocked on my neighbor's door to ask him if I could borrow his scissors, and to my horror he appeared at the door completely naked with his hand on his penis and promptly ejaculated in my eye, shouting, "Surprise Party!"

When a lot of people you don't know show up at your house because they heard you were having a party.
Person #1: Dude, last night was such a surprise party!
Person #2: I know! Where the fuck did all those people come from?

MUST BE DONE WITH LIGHTS OFF! When a male pretends to have penetrated a female's vagina with his penis but in fact has inserted a life-like dildo (works best from behind). He proceeds to fake intercourse for a period of time, using the dildo all the while, and suddenly, falls off the bed with yell while leaving the dildo deep in the vagina. The male then turns back on the lights and yells surprise!

When you think you took a quick, little shit and then look down in the toilet bowl afterwards and it's the biggest log of shit you've ever seen, Surprise!
I was at a party at my friend's house and really had to go, little did I know I was in for The Surprise Party that clogged the bowl.

After being rejected sexual release from your parter, you wait for them to fall asleep, elavate to your haunches and stroke your donger until you are ready to ejaculate.... at that moment you slap them in the forehead and yell "surprise" as you paint your load across their unsuspecting face.

Dale " no but when she fell asleep I gave her the ol' "Okeana surprise party" and then wiped my dick off on the curtains"
