Gap-flash

When a woman (or possibly a man) wears a button-down shirt that is a little too tight, resulting in the fabric straining at the buttons, and forming a gap. This allows friends, family, and/or the general public to have a glimpse of your side-boob.
"Oh man! That girl should really put a sweater on."

"Why?"

"Because she's totally gap-flashin' the entire coffee shop!"

Flashing Fireman

A playful, titty-powered kink where someone gets turned on by flashing their boobs at firefighters—often as a cheeky thank-you for being hot in every sense of the word. It’s fun, flirty, and a little bit unhinged. Sirens go off, shirts come up. Everybody wins.
Flashing fireman isn’t about starting fires—it’s about rewarding the ones who put them out… with titties.
