A trashy tattoo that follows a woman's curves under her breasts, the way an underwire in a bra would. The 2000' tramp stamp.
When you meet a tatted chick with an underwire, you know she's easy!
When a mask 😷 that is worn to protect others from getting airborne illnesses is worn UNDER your nose.
“Wish that dipshit would fix their nose-underwire so I don’t get sick!”
