TLA's (well just A's really)

Some times Three Letter Acronyms get a bit overwhelming. Just when you think you;re on a roll you get one that really stumps you.

Well I get that LAG = loose aggro and that;
TAG = tight aggro
SSHe = small stakes hold'em (2+2)
GSHE = getting started in hold'em poker

however there are a few that I just can't get the major one is TOP. I'm not going to bother you with my silly guess, I just can't get it. The other one is WxxHE something.

Thank you I would appreciate any and all replies
