Hacer chupe
Hacer chupe is when you make someone blow you like you're the most powerful person in the universe. It's basically the school version of a royal punishment.
Blow a kiss and say, 'You're my slave for the rest of the year.'
Make a kiss sound and drag someone into a fight in the middle of the hallway.
Blow a kiss and tell someone, 'I'll beat you up if you don't do what I say.'
