(verb) To take a slightly unattractive girl to a sleazy pizza place after drinking heavily, not order any pizza, but instead make out with the girl in the corner while shitty music plays and the counter-attendants look on unhappily. One who jumbo slices will not take the girl home after.
Mikey's hitting on every girl at the bar tonight. He must really be trying to jumbo slice!
