“Tap” is being used as a noun here. It took me a bit to get it.

To add context, here is a broad count of Karl’s video topics over the past year (going back to May 29th):

Celebrate: 8 (5.83 million views)

Bash: 13 (18.5 million views)

Billy (all negative): 12 (8.5 million views)

He’s definitely leaned more into the Billy drama / exposing cheaters & fakers over the past year. People seem a lot more interested in the “expose” videos, so unfortunately it makes sense for him to make more of those.
