look up any word, like smh:
 
1.
A hangover spent with the gang you got drunk with.
Friend 1: I've got a hangover.
Friend 2: So do I.
Friend 3: I also feel unwell.
Friend 4: Why did we get so drunk.
Friend 5: Why? Just Why?
Friend 1 (again): It appears we have a gangover.

2.
When you wake up the next morning after a drunken night and find multiple males hanging their flaccid wangs over your face.
Premal: Hey man, how was the party last night?

Colter: Not bad, except the fact that I had a multi-racial gangover this morning.
