face-mash
When you grab someone's face and slam it into your palm like you're trying to flatten a piece of pizza. It's not a slap. It's a full-on face attack. It’s the worst thing you can do to someone who’s already mad enough to rip your hair out.
Bro, you called my mom fat. I face-mashed you so hard your nose went on a diet.
During lunch, I face-mashed my crush because he said my hair looked like a raccoon's nest.
At the bus stop, I face-mashed my brother because he ate my last taco.
