Shark Attack

When you have a girl laying on a bed, naked, and you surprise her by sneaking into the room, while prone, and jumping up to give her oral sex.

Dude: How did you like that Shark Attack last night?

Girl: You scared the Shit outta me!

Shark

You know damn well what a shark is. You searched urban dictionary on urban dictionary because you're bored.

"Shark" is not a god damn sex act. "Sucking a dick." Is a sex act, go get out there and do some sex acts instead of looking at urban dictionary.

Virtue Shark

An internet user (usually on tumblr, discord, or reddit) who makes convoluted claims that a group, event, or idea is morally wrong in order to make themselves seem morally right. Most of the times, their methods involve claiming that something completely innocent and irrelevant is bigoted in some elaborate way. They are common in fandom spaces.

"I've been getting so much hate for writing characters X and Y as romantic in my fanfiction because some virtue shark had to accuse me of "perpetuating the belief" that male and female characters can't be friends. That's not even something I said!

Shark

A word with millions of UD entries complaining about how they didn't find some sexual definition. Yes, i know a shark is a fish, there's no need to tell me that every time.

UD entry #1: an animal who lives in the ocean, what were you expecting you dirty minded person

UD entry #2: a shark is not a sex position, it's a sea creature with lots of teeth

UD entry #3: scary water guy. i bet you thought you'd find a sex definition.

*no actual sex entries*

reverse shark attack

when you stick a knife handle up your friends ass while they lay on their belly, so the blade sticks out like a shark fin. this makes them crawl across the bed squirming back and forth whipping their feet side to side like a shark

i walked into to andy’s room and noticed that they had just been reverse shark attacked as they whipped across the bedroom
