Underwearassment 

Imagine yourself comfortably walking around your house in your underwear when suddenly someone starts pounding on your front door. Underwearassment is the term used to describe the irrational panic you feel as you frantically search for a pair of pants and yell through the door that you will be there in just a second. More often than not you will never find a pair of pants and settle for a blanket or a towel.

Jane felt a frightening sense of underwearassment as she wrapped a towel around her waist and opened the door for Dan.

Underwearing 

Wearing so few clothes you might as well be wearing only underwear.

Girl: that girl's clothes are so skimpy, she is such a slut
Dude: yeah, love it when girls go around underwearing.
Other dude: yes, girls that underwear as so sexy.
