Get the retarsion mug.
To intentionally fail to be helpful to, or otherwise passively exacting revenge on, a tight ass or rip off artist, usually at their financial expense.
I bought the first round of drinks with Doug last weekend after which Doug insisted we each buy our own. What a fuckin tight ass! But I retarsed him yesterday when I watched silently as he paid $1500 for a new TV which I knew was on sale at a different store for $1000.
