a handful
When two people are so in love they could kiss in public and not care if everyone laughs at them.
My sister and her boyfriend are a handful. They hold hands in the grocery store and make out in the car.
My mom and dad are a handful. They dance in the kitchen and sing show tunes at 2 a. m.
My uncle and his wife are a handful. They text each other during family dinners and forget about us.
