Undies 

Underpants (usually of a female). Originally an Australian slang term, Americans are finally picking it up due to the word ‘panties’ being creepy AF.

“My undies are riding up my bum.”

Last Chance Undies 

Your last pair of clean underwear, reminding you that this is your last chance to wear any unless you get your laundry done; that pair of ugly old underwear that you reserve for an emergency.

Dude, I gotta do laundry today, I've got my last chance undies on!

edible undies 

Undergarments that you can eat. The consistancy is similar to fruit roll-ups.

I bought some edible undies, but I got stuck in traffic and ate them in the car.
