How do you keep hard liquor?

Invite a lady-friend over and ply her with your wares 'til she's in the mood. Repeat with the same or different lady-friends 'til the liquor's used up.

Have a party, mix up pitchers of drinks and let friends and neighbors enjoy it. You'll increase you friend count that way.

Better yet send it to me. Just joking.

If you absolutely MUST waste it, pour it down the drain or on the ground or in the street and it will evaporate.
