Why are people using euphemisms here? The sexual reference: WAP stands for "wet ass pussy", popularized by Cardi B: https://www.youtube.com/watch?v=hsm4poTWjMs. The music video has over 400M views.
Apparently I've now lost that game.
The term (as a word, not an acronym) is also used to refer to self-indulgence, generally among males. That and earlier references suggesting various modes of beat being laid down are what I was referencing with my etymology link above.
Wonder if that word is where 'fap' comes from (meaning 'to masturbate')
If there is one thing that really educated me about kink, it's that comic
Cool!
