What does 25BB/100 stand for, anyway? I've been seeing that around a lot lately but I haven't seen anybody explain what it stands for.

Today I've been doing pretty good. I'm up to about $33 today. I'm not sure what I started with though, I forgot to look, but I want to say it was around $25. Not half bad considering how I've been running lately. I've been playing an extremely tight game today. I don't know what my stats are for the whole day, but in my current session of about 166 hands I'm at 23/14/2.6, which makes my claim of playing extremely tight sound kind of hollow, but I've had a good run of cards, and it's a small sample anyway.
