Rapper Travis Scott -- Lunges at Fan ... I'm NOT A$AP Rocky!!! (VIDEO)

Travis Scott lost it Thursday night when several fans mistook him for A$AP Rocky.

True enough they have similar hairstyles, but it's clearly a sore spot for the rapper, who was going into Up & Down nightclub in NYC for his album release party.

It was a big deal for Travis ... Bieber and Kendall Jenner were inside to cheer him on, but he had to shake off a case of the angries before entering.

As for Shakespeare's question, "What's in a name?"  Now we can answer ... everything.
