Unbench the Kench 

When you're playing League of Legends as Tahm Kench and you bust out the big guns to go swallow up the enemy team's carrying player before spitting him out into the middle of your team for you all to dog pile onto like they're delicious BBQ chicken wings.

Also relevant if everyone is dead, you're 1v1'ing a fed Nasus and you gotta kill that fucker before he Q-slam 1-shot's your nexus.

First quoted by BrickyOrchid8 in his Story Time video 'Unbench the Kench'.

It's time to Unbench the Kench!

"Oh, really? I thought this would be easy considering I've never done this before," Harry breathily shoots back. "Fucking moron."

"Are you going to shut up and let me fuck you?" Louis snaps. The floor is cold, but Harry's body is radiating heat from everywhere, and it's making Louis even more frustrated.
