A song by or for drunk people, to be sung wile drunk, drinking, or thinking of drinking... Sometimes it is for merry-making like Mary McGregor or In Heaven There is no Beer, or for wallowing in like One Bourbon, One Scotch, One Beer.

Some, on the other hand, are just plain silly like the Philosopher's Drinking Song of Monty Python origin. Some are distincly Irish like The Night Pat Murphy Died, some are distinclty American like the Ramones song Somebody Put Something in my Drink.
