The sexual act, in order, where one ejaculates on their own penis, sticks it in their partner's ass and gets it covered in poop, and then stick the whole thing in his girl's vagina when she is on her period. each forming the ice cream, chocolate sauce, and cherry on top, respectively. The girl will then suck it all off, including his nuts, since no sundae is complete without nuts.
Did you hear what happened to Adam? He and Jamie tried a Sundae Surprise, now she has a UTI and he has shitdick.

When a bunch of dudes stand in a line and jizz on one guy and one of the dudes in the line pees (aka the surprise) on said guy.
“I just got a yolky surprise from my teacher!”
“That’s so funny because I just gave a yolky surprise yesterday and I don’t think the ‘yolk’ is supposed to be red.”

I only turned my back for a second; when I turned around Manual had initiated a Nicaraguan Sibling Surprise on Isabella. She lucky that he only peed on her back.

When a man is plowing a woman from behind and is about to ejaculate, he spits on her back to have the woman believe he has finished. When the woman turns around the man dumps his backed up load into her eye followed by a kick to her shin so she hops around with her hand on her eye and screams "ARGH!!".
