This mod in particular is called jailbreak and it's where I learned all the crazy stuff like bhopping. This is in CS source, but Jailbreak is on pretty much every other moddable source game too. I think it started as a quake 2 mod.

edit: The current server is called Oceanic Servers Jailbreak. This came from Domination Servers, being briefly named Backlash Gaming, and before that Momentum Networks, and before that it was Freedom Gamers. That's the one you see in my original CS:S jailbreak video: https://youtu.be/56RQp8lq_sU
Before that it was Xtreme Jailbreak (XJB) https://www.youtube.com/watch?v=OT2Y4_J1ee0
and before that Missing in Action (MIA)
