A super cheap airline ticket, usually occurring when an airline leaves a zero off a price, or prices a ticket in Yen instead of US Dollars.
Alitalia had one of the best Jumbo's in 2006 when they sold a business class ticket Toronto-Cypress for only $33, plus tax! It was supposed to be more than 100 times more expensive.

(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.
