This Fan Knew All The Words At The Young Thug Concert, And Got REALLY Lucky

Come prepared.

CHICAGO -- Rap fans and listeners like to joke that Young Thug's lyrics are often indecipherable -- and let's face it, it does often take multiple close listens to figure out exactly what Thugger's spewing -- which is what makes knowing all the words at a show that much more impressive.

Despite the difficulties, there were a handful of people at Grant Park in Chicago for the first day of Lollapalooza who were able to go bar for bar with Thug. And one fan in particular got singled out by the Barter 6 rapper for his in-crowd performance.

The result? Thug brought him onstage during "Danny Glover" for some joint rhyming, selfie videos, and a perfectly timed crowd-surf.

And here's a look at the epic surf from the stage.
