A naked lap happens in a drinking game/bar sport when one person achieves the winning score while the other person fails to make some minimum number of points.

In ten-cup beer pong for example, if seven cups remain on the table at the end of the game, the team with seven cups left has to run a naked lap.

In pool, a 7 Ball Loss (pub/taven pool rule) is usually grounds for a naked lap.

Many rules have been established for other common sports such as darts, foosball etc., but the threshold for naked lapping tends to vary from venue to venue.
Bro, I naked lapped Marcus in pool yesterday.
