My school is extremely strict. One night I told a rushee as I was bumped(as in rotation), "Ok, I'm sure I'll see you around school!" That was considered an "oral bid." Anything can be construed as an oral bid now. It's insane. So like some of you others, we have to say "Have a good night" "Enjoy the rest of rush, " etc. It's so horrible that out of habit when we leave someone, we instinctually tend to say "see ya." Bam, oral bid. I know, I know. So at one party one of our girls accidentally said "See you, " but tried in vain to recover by adding an "re way to the door!" As in "See your way to the door!" Haha. It was hysterical, as we all witnessed the rushee's expression.
PS: Dirty rushing is illegal, but chantilly, it's a good sign!
