After coming to VidCon every year since the first, iSekC brought the HEAT to VidCon 2014.
His name originated when he was a kid and wanted a weird way of spelling sexy.
"It's better than cool123 or whatever other kids were calling themselves," iSekC told us.
He's expanding by also creating a gaming channel.
"When I started, I did spoofs, parodies, music and made fun of pop culture. I've tested everything and seen what works and what doesn't," the YouTuber told us. "Over time, I've developed a format and also have a gaming channel, which has surpassed my comedy channel."
Check out his series, "thug life."
