Trouser Butterfly

A slight fluttering sensation felt in the flaccid penis as it starts becoming erect during normal everyday activity or while seated, usually as a reaction to some kind of unanticipated sexual stimulus. The trouser butterfly is also associated with a very slight movement of the penis as the erection progresses, making a noticeable movement through the trousers / pants.

Did you see that gorgeous new receptionist? She was so hot it gave me a trouser butterfly.

I got a trouser butterfly on the bus this morning because the seat was vibrating so much, and I'm sure the woman sitting opposite noticed.

Sandra asked me out for a drink at lunchtime - it gave me a trouser butterfly just thinking about it!

butterface

Butterface describes a girl that when seeing her from behind, you think of committing crime, but after seeing her face, you think of self-defense.

I saw this hot chick walking in front of me, so I picked up my pace and caught up with her. When I looked back to check her out, my feet were busy peddling back. What a disappointment, she was a butterface.

Butterfly Cuddle

We all love cuddling somebody before we go to sleep, but when you actually pass out, it's time to go ass-to-ass, and take over your separate sides. From above, you look like a butterfly!

"Dude, I love cuddling her but when I'm about to pass out, we just butterfly cuddle"
