Panty Drop 

When a girl moves her panties down and they fall to her ankles. This may be also happen when she slowly takes them off. At this time, the vulva is now exposed. Sexual intercourse may now take place. The panty drop may occur due to the girl being sexually excited and ready to engage in sexual activity.

I played a jazzy song and my girlfriend liked it so much she did a panty drop. My friend played the song for his wife and she did the same thing.

Each box is a surprise with gorgeous styles for everyday sexy and everynight sassy, selected based on the customer’s panty profile.

drop your pants 

Originally started to define a rebelliously-silly style of Punk music (ie NOFX, Propagandhi, Vandals) but now extends to anything political which doesnt take itself intirely seriously.

"this song is so drop-your-pants"
"it's drop-your-pants!"
"I'm gonna drop my pants for the government!"
"Noam Chomsky is a drop-your-pants kinda guy"
