To cuddle in an overly aggressive fashion in which the "big" spoon place one arm around the "little" spoons neck slowly suffocating till an existential bliss is reached.
Person 1: Did you reach second base with Mandy?
Person 2: No, but there was some crazy "chuddling" going on. I know she liked it.

Person 2: Because nothing says i love you like their eyes rolling in the back of their head.
