pyuk

Used to describe a sick feeling or disgust in something.

I've felt like pyuk ever since lastnight's party.
Alternatively;
Bob: So did you meet that skank you talk to on MSN?
George: Dude, pyuk.

Pyukumuku 

The Pyukumuku is a water-type Pokémon that strongly resembles a certain type of dildo that has pink ribbed spikes. The Pyukumuku can regurgitate its innards, which is a joke among high school students as it sort of resembles jizz. The Pyukumuku is a sea slug and can be found on Route 7 in the new Pokémon game. Among its moves it can learn Harden, Endure, and All-Out Pummeling.

Wow, look at that Pyukumuku's spikes, the lucky trainer must be very happy with her discovery.

Pyukcord

A server for the Pokémon battling simulator, Pokémon Showdown. It originally started as a group determined to get the Pokémon Pyukumuku to OverUsed, a tier where Pokémon who are used very often reside.

“Did you hear about how the people in Pyukcord planned on getting Pyukumuku into OverUsed?”
