Me and my friends invented this one.  The game is called 'Four Of A
Kind'.  The object of the game is for one team to get four of a kind
first (4 cards with the same value).  You need a full deck of cards with
no jokers and four people.

Create 2 teams of 2 people and sit directly across from your teammate. 
Shuffle the deck and put it face down in the middle of the table.
Then spread all the cards out.  One person goes first and selects a
card from the pile, flips it over  and places it in front of him for all to see.
Then, in clockwise order the next person goes from the other team and selects a card.
What you're trying to do is pick cards that match what you or your
teammate has or "Burn" your opponents cards.  If you match up cards then
put the pair together in front of you or your partner so it's easier to see.

To explain the "Burn" lets say your opponents have a pair of nines and you pull a 
nine from the deck.  This means that there is no way that your opponents can
get 4 nines because you have one.  So the opponents drink 2 drinks for
having a pair of nines (1 drink for singles,3 for triples) and you and
your opponents discard your nines to the "Burn pile".  The "Burn pile"
should be placed face up so you all can see what cards are "Burned".
Now whatever team draws the last nine has to drink for drawing a
"Burned" card.  This game goes on until one team has four of a kind,
when this happens the opponents have to drink as many drinks as there
are cards left in the middle.

If no one wins and there are no cards left in the middle then
the game starts over.  So you drink when you pick a "Burned" card,
or the opponents "Burn" you.  Play it and let me know if you have questions.
