PS2 Expansion Bay Hiding Spot 

On a PS2 (the fat model) there is an empty slot in the back meant to put in a hard drive and network adapter, this empty spot can be accessed by taking off the network adapter or cover on the back. This is a great place to hide stuff like your weed, cigarettes/cigars, cans of snuff, small flasks, money and electronic devices etc. It's a great hiding spot because nobody will think to look for anything strange in there(just make sure to close up the back after) and no one will suspect a thing!

Person 1:"I need to hide this herb somewhere for a bit!"
Person 2:"Put it in my PS2"
Person 1:"How the fuck would i do that?"
Person 2: -opens the back- "See?'
Person 1:"ABSOLUTELY PERFECT!!!"
Person 2:"Yeah the good ol' PS2 expansion bay hiding spot trick!"

Hyper expansion 

A weird ass fetish were the artist draws tits that takes up most of Earth or a dick the size of Jupiter. Then, they slap any fictional character and call it "art" because the artist is so fucking lazy. Come on, if you're going to draw big tits or cock, at least don't make it take up the entire picture

Dude 1: Dude, I just found this hyper expansion picture of Amy Rose here. She's got tits the size of the fucking sun

Dude 1: furaffinty.net
Dude 2: Because of course it is
