painting her fingernails
Painting her fingernails is when a girl flashes her nails like she just got a manicure, but it’s really just a sneaky way to show off how good she looks while pretending to do something else.
She was in the bathroom at the bar and came out with a glossy smile like she had just won a beauty contest.
At the grocery store, she opened her phone like she was texting, but it was really just so she could show off her nails.
During lunch break, she sat across from me and slowly peeled back her nail polish like it was a secret.
