Yeah, RainMan, it is common for members of greek-lettered organizations after they sing their hymn/song, to do their party walk thang...during the reception!
HOWEVER, I have NEVER seen other greeks stroll/party walk at the same time...
From all of the weddings I have attended, it is only for the bride and/or groom's respective organization!
I know for my wedding, I wish some other sorority person would get on the floor "doing their thang" or doing their call....
THAT'S JUST DISRESPECTFUL!
I'd have to have them escorted....OUT!
I won't have to worry, cause folks know I don't play that...
