A shot of the worst brand of tequila the bar has. Usually given to enemies, d-bags or just your idiot friend.

One usually proposes a shot and orders one rusty bucket and one good shot that looks like a rusty bucket (usually whiskey/vodka depending on color of tequila) so the other party is none the wiser.

After a set amount of time passes said target usually forgets so you can purchase another rusty bucket and propose it as an apology and punk them yet again.
Example 1:
Person 1: See that douchey bro by the bar
Person 2: Yea? Should we mess with him?
Person 1: Yeah, Go buy him a rusty bucket. That'll have him puking his brains outs
(Aforementioned Bro will be to douchey to realize what has transpired)

Example 2:
Idiot Friend: Ughh man wtf was that?
You: You just drank a rusty bucket dumbass!
