Ear Tug
A gross, finger-based announcement that you're so head over heels you're practically drooling.
My bf tugged my ear during class because he couldn't wait to kiss me after lunch.
She pulled my ear so hard during the Zoom call, my mom walked in and thought I was being tortured.
He tugged my ear during the game and said, 'You're mine now, and you're gonna stay that way.'
