Any drinking games for 2 couples?

A friend and i are planning to do like a double date in my house next saturday, for Valentine's Day (yeah.. cheesy i know), and we're planning to drink off course, so.. i was wondering if there were any drinking games to play with your couple versus the other couple..Any drinking games for 2 couples?
KINGS CUP. The funniest game to play ever. can be played with 3+ people.


You will need. deck of cards, beer or whatever you want(beer is probably what you want to play with though), a big cup for liquid.


the rules are as follows.


you have the cup in the middle of the table, with the cards spread out surrounding the cup.


cards have meaning.


2 for you(pick someone to drink)


3 for me(you drink)


4 whores(ladies drink)


5 Thumbs ( the puller of this card has all the power, they put their thumb on the table and the others follow suit, last one to do so drinks Twice!)


6 dicks(guys drink)


7 heaven(same as thumbs except you raise your hand in the air)


8 pick a mate(pick a person and from then on they drink when u do)


9 bust a rhyme (one person says something and the next person to the left must rhyme, the person to screw up drinks twice)


10 categories( pick a category eg types of shoes, types of meat, hair colors. person who cant think of something within the category loses)


J waterfall(card puller starts drinking, person to left follows and so on until first person stops and next follows suit.)


Q Questions(ask a question, anything, to a person and anyone who cant ask a question to someone loses)


K Make a rule(U can make a new rule for the game eg u cuss u drink, everytime u drink u must say AIIIYYY! whatever, u must also poor any amount of your drink into the cup in the middle of the table.)


A social(everyone drinks)


This game is so fun to play once everyone understands the rulesAny drinking games for 2 couples?
