My sister has applied other creative uses for the small plastic cups. She puts her home-made jell-o shots. That's nearly sacrilegious I suppose. But that's my sister.
She has her theory as to the difference in the way a man vs. A woman drinks a jell-o shot. She thinks that a woman places the entire cup in her mouth and sucks out the shot. On the other hand, a man puts his tongue into the cup and pushes out the shot.
Personally, I use my tongue. You read into that any way you want....
