At a party. Drink a buncha alcohol, smoke some weed, trade host of party 'paying me back for the concert tickets I bought us' for leftovers of a bottle of vocdka. Go to front room to crash with straight best friend. Instead drink vodka. Straight friend offers to show me his junk.
See straight best friend's junk. Awkwardly compliment. Embarassing for him when he remembers. Good manners say I should offer to return the favour, he declines.
