Get the nasty mug.
To be:
A- Disgusting, vile or lewd
B- Rude, impolite, or extremely offensive in conduct towards another person
1. LaWiesha is nasty; don't drink out of the same cup as her or borrow her toothbrush

2. Jerk-off At The Osco- Whaddya mean you don't carry ___?!! *shoves cashier* What the heck kind of sorry excuse for an Osco is this!?
Cashier- I'm sorry, but we ran out yesterday. There's nothing I can do about it now; the next shipment isn't due in for another 5 hours....and being a nasty, arrogant jerkoff won't expedite the process, either!
