Now from what I can tell we all have different methods of dealing with this problem. At my chapter, we generally have our parties at a club and there are usually people there who aren't greek or in college so we keep the strolling to a minium. We usually don't wear 'naila, but you catch on when there are several women in a line dancing (duh).
If someone chooses to break the line they get the look-> the explaination-> then the diss if they don't get the point. Usually, we don't bump or push cause we don't know how crazy these people are. Strolls aren't worth getting shot over. We also tighten the line and if someone jumps on the end we try to close off the line so the last person is not strolling or again with the explaination or the dirty looks.
Funny story though. We were at a club, broke into a walk and an older, and I think foreign, gentleman tried to dance/flirt with the girls at the end of the line. He grabbed our hands and tried not to take no for an answer. We kept trying to get away from him but he followed us ALL OVER THE CLUB! I mean dang, get a clue!
