Intentional or not, WAP (Wiresless Application Protocol) was a real protocol that allowed you to surf the web on a cellphone in the late 90s/early 20s, before 3G was a thing. Most websites (or wapsites) were super barebones and relatively fast for me, and you could find interesting stuff like cracked .jars of popular games or of course, porn. https://en.wikipedia.org/wiki/Wireless_Application_Protocol
They had to be barebones. WAP only supported text and tiny black and white (no greyscale) images. I did some WAP sites and it was pretty horrible to work with even back then. The phone I used (Nokia 7110) didn't even support GPRS so you had to make a call at 9600 baud and pay per minute so you didn't want to hang around either.
The Japanese had i.mode which was much more powerful. They tried to introduce it in Europe but by then the smartphone was already coming.
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.
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.
"Fap" began as onomatopoeia popularized by the Sexy Losers webcomic, first appearing in https://www.sexylosers.com/comic/003/ (NSFW in case that wasn't obvious).
If this was an intentional pun over the recently-acquired other meaning of "WAP", my compliments, it was perfectly executed.
