Is there a word for the uncanny ability to find one's way home when extremely drunk?
Solution 1:
Beerdar - as in beer-radar - although, that could just be something me and my student friends came up with.
Solution 2:
Not a one-word answer, but maybe "homing instinct"?
Solution 3:
One suggestion made during the dispute was "beer compass", but it was claimed that meant the same as "beer goggles".
