look up any word, like bukkake:
 
1.
Before having gay sex, a way to determine who is on top and who is on bottom. Derived from the term "drop the soap" but in this case the result is desired.
Straight guy: "How do you guys figure out who is on top or who is on bottom?"

Gay guy A: "Well, we lock eyes. Whoever blinks first is on the bottom."

Gay guy B: "Yea, either that or we play toss the soap and the first person who drops it is on the bottom."
