Warning: Video contains explicit language

Brock Lesnar didn't mince his words when asked about UFC featherweight champion Conor McGregor ahead of SummerSlam.

McGregor, who's set to face off against Nate Diaz at UFC 202 on Saturday night, has taken repeated shots at WWE's current roster of stars, calling them "dweebs" and "p---ies."

In an interview with SiriusXM's Sam Roberts, Lesnar echoed the sentiments of Seth Rollins, who challenged McGregor to show what he's got in the WWE ring during a Friday appearance on ESPN's "SportsCenter."
