Farfullero
A person who makes a flashy show of being at a party, orders food or drinks, and then slips away, leaving the bill for their friends to pay. They typically use excuses like: I am going to the bathroom, or: I will be right back, to ditch out. (This involves making an aguaje, which is a Dominican term for putting on a front or bluffing to impress others).
That guy is a farfullero.
