Trouser Towel

The act of wiping wet or damp hands on the bottom of your trouser legs.

Usually performed in the presence of pathetic hand dryers in publice toilets, so can be used often .... Especially around where I live ¬¬

Person 1: Hey dude, did you use that hand dryer?

Person 2: No man, it was pathetic, had to use a trouser towel.

Person 1: Same here dude, it SUCKED!
