Threewave

Threewave is a formerly popular Quakeworld mod that made CTF mainstream in shooters throughout the late 90's. The mod is notorious for its usage of table-turning runes, a grappling hook, and an explicit objective. To avoid the problems of people "choosing" an offensive or defensive squad within their team, there have been suggestions for the one-flag variant, but Zoid, creator of the mod, et al. didn't start listening until Team Arena.

JC Denton: Hey, could you go and tell Gunther that his blue popcorn is ready?
Paul: I'm not your pet, JC.
Denton: I've got a new Threewave server running after work hours and I'm only going to tell you the password if you do it.

Three year old child spouting attitude like a spoiled teenage.

Admiral's Threeway 

An amorous encounter with a mother and daughter.

The name comes from Admiral Nelson's well know proclivity for mother/daughter combos.

Last weekend, I went home with this smokin' hottie. It was getting hot and heavy, when her mom busted in. Before I could say a word, this little cougar jumped right in. Just call me Lord Nelson, cause I had an Admiral's Threeway.
