To crash ones performance/event by jumping on stage with performer. Usually accompanied with the fact that they are in no way supposed to be on stage. Origin comes from Jay-Z remarks to Lil Mama crashing his performance at the 2009 VMA's

To rudely interrupt somebody while they are busy doing something important. Like T Pain did to Jay Z at Hot 97 Summer Jam, crashing the stage like shit is sweet. Later done to Jay AGAIN buy Lil Mama at the VMAs. This is where Jay coined the phrase, '' You T-Paining Right Now''.
