Gamma Tester

Someone who receives their Amazon game pre-order early, so they can give feedback to the developers before the official release date.

I got Yakuza Kiwami on the 26th of August even though it was officially released on the 29th. I guess they wanted me to be a gamma tester for the game.

Undercover Wank

When it's so cold in your bedroom, you have to keep the duvet on while you beat off

"Man, it was so cold last night, I had to have an undercover wank!"

Hate Sink

A Hate Sink is a character in a work of fiction that has been deliberately written to be so irredeemably vile and unlikeable that the audience wants said character to fail.

Saki's Mother in the game Yakuza 3 is a total Hate Sink; they didn't even bother to give her a name in case it made her relatable in any way.
