When someone lies to you and gets away with it, especially if they brag about it to someone after. The
act of being grubered is
grubering when someone is in the
act of trying to pull one over on you.
Greg was grubered by John when he bought his neighbors lawn mower, then found out how poorly the mower ran.
Later, John was bragging to Nancy about how he had grubered Greg. When speaking to a friend about a transaction you
think they were ripped off on. Aw
man, you've been grubered!
