Brainrot marketing

so today i was on my break and decided to open instagram, INSTAGRAM not even tiktok, just to kill time. Literally like 3 reels in, i get this reel or "ad" allegedly targeted at "men's health"?? and istg i don't even wanna believe it's real because LORD HAVE MERCY So the video went like this:

It showed that tiktok dance trend with those brazilian songs, yk the one with the arm movements and wtv brainrot nonsense, but apparently now they do the 67 with their hands too or some stupid shit like that. Right after showing the dance, the presenter (or wtv she was) goes: "Just like you love doing the 67, have you done 67 to your TESTICLES yet??" WHAT THE ACTUAL FUCK IM CRYING

first of all, what does "doing 67 to your testicles" even mean??? Is it some kind of testicular massage to relax your balls or make sperm flow better?? and second of all, WTH IS THAT AD?? How did the people who made that look at it, approve it, and say "Oh yeah, fire line, the audience is gonna love this" I'M CTFUUU , that shouldn't even be legal jesus
