I try to use the same in forums as my notes system says:
- (standard) reg, like 22/18 w normal postflop stats
- aggro reg, 28+ vpip and high pfr combined w high 3b/postflop freq
- nit reg, 18 vpip and under, high fold to steals, fit/fold postflop and so on
- recreational, which usually is gonna be passive fish w 30+ vpip and low pfr/3b/postflop stats, or if I know he plays like max 2 tables but has reggish stats but will do weird stuff from time to time
- whale / aggro / spewy fish, like the 60/30 guys or the 85/5 callingstation type
So yeah to answer your question, if someone says recreational I think about fishy players who don't take the game too seriously.
