Snick the Porcupine

Snick is a purple porcupine from Pizza Tower, a work in progress game by PTG. He's a joke character of sorts portraying Sonic the Hedgehog, and this is even joked with by Peppino (The main character) accidentally going to the Snick Amateur Games Expo, instead of the Sonic Amateur Games Expo. Snick is a goofy little guy.

Yo, is that Snick the Porcupine from Pizza Tower?
Yeah, bro.

Awesome, he's so fucking cool.

The Salty Porcupine 

While engaging in sexual activity with a woman, pull out your cock and slide your fist into her pussy. After sliding the fist in open all five fingers and thrust your hand up and down as fast as possible creating a porcupine-like atomosphere.

Joe opened up his hand inside her and made her feel the essence of the salt...

Brad: Yea, some sort of linguistic genius posted it on urban dictionary ( ͡° ͜ʖ ͡°)
