Grooligan 

A person or group of people who respond to a discount deal through Groupon and display rude or unruly behavior when they visit the local business that created the promotion.

Similar to hooligan, the grooligan looks for the cheapest deal then crashes the local establishment with or without other grooligans expecting to be treated like a preferred customer while paying almost nothing.

Alternate spelling: Grouligan

Don't run that Groupon promo for the game dude, you will only get Grooligans in your bar.
