One who consistently rapes the nacho plate. This person shows a total lack of regard for the other people sharing the nachos, they take all the cheese, meat, sour cream and salsa without batting an eyelash. They often take the nucleus chip of the nachos, thus ruining the appetizer all together leaving only nacho shrapnel for the other poor bastards at the table.
Tara: Do you wanna order nacho's?
Sabrina: Naah, Jess is meeting us and she's a TOTAL nachosaurus!!!!!!
Tara: True DAT!!!
