Not so R rated, but still pleasantly fun
some of the teams I've had:
We let boys play, too! (one guy, 7 girls)
No D like Self D (coined by my wife after she hooked herself on every shot, really, every shot, in one match)
was it good for you? (not actually dirty but i don't know if the APA would let us take it to nationals)
put it where? (one of our players found a wooden coin somewhere that said "put it here", so she used it as her pocket marker for a session. we qualified for cities so we changed the name. goin' to vegas in august! i guess the name worked for us)
what's in your pocket? (i think it's a take on the commercial, i dunno, i like it)
some other names i like:
the balls have eyes
a-rack-no-phobia
2 gods and 3 hail mary's (two APA 7s and three APA 3s)
