What is Hummbler?

When you are on a first date or you just brought home a girl from a party, and she starts going down on you, and just before you cum, she pulls out her penis.
Stephan hasn't left the house since he got a hummbler when he went to that volleyball party.

2.
A huge ass vehicle that gets eighteen gallons to the mile, is extremely uncomfortable and makes you look like a arrogant duece. If you own one of these I hope your family disowns you. If your friend has one then burn it, if your dad has one, beat him with a large Ramen noodle, if your mom has one, then you must be one mo' fugly monster of a child.
