To Come or cum.
Created during class by two highschoolers.
While practicing substitutions for the word "said,"
like "barked" or "screamed,"
the teacher brought up quailed (past tense)
and it became an instant classic.
"say my name!" matt bellowed
"MATT!!" Becky Shreiked.
"O shit!" bellowed matt as he proceeded to quail all over becky's face.
I smeared my quail on your daughters face last night.
Have a nice day.
(Merriam-Webster online Dictionary, 2007)

wimp: "ahh! i don't want to go in there"
brave person: "stop quailin'. let's go"
