KSI Trolls IShowSpeed After WrestleMania Beatdown, ‘Sucks Doesn’t It?’

Talk about adding insult to injury — IShowSpeed‘s pain continued after getting destroyed by Randy Orton at WrestleMania 40 … ’cause KSI made things even worse by heckling him over the epic ass-kicking.

The popular streamer made a surprise appearance during Logan Paul‘s match against Orton and Kevin Owens on Sunday … revealing himself as the guy in a Prime bottle costume.

Speed took quite a beating throughout the showdown … with Orton viciously kicking him and hitting him with a signature RKO, which took him out.

Speed appeared to be in major pain after Paul retained his United States Championship … wearing a neck brace and lying on a cart.

Paul’s former boxing nemesis-turned-business partner played a similar role for Paul at WrestleMania 39 … which resulted in the Maverick accidentally body-slamming him on a table.

With that being said, KSI was quick to throw some verbal jabs Speed’s way as he nursed his injuries backstage … sending the streamer a personal video message.

“Speed, I hope you enjoyed your WWE debut,” KSI said with a laugh. “I hope you enjoyed getting wrecked. It sucks, doesn’t it? It’s not fun.”

“Anyway, IShowStink, IShowMeat, well played on getting your ass beat. I’ll see you in a bit.”

Speed was NOT happy about the clip … shouting back into the phone, “Man, f*** you, you bald-headed bitch. Man, get the f*** outta here, bro.”

As for how Speed’s feeling physically, he said wrestling may be scripted, but his owies are REAL … revealing his neck is messed up and he had the wind knocked out of him.
