This appeared in a review but I couldn't find it in the Acronym manual or at Urban Dict. I don't think its a typo b/c he used it 3 different times. Before I email him for an explanation, I thought I'd expose my ignorance here.

Hmmm......Bareback Lick Job? Maybe a term for extreme DT, as in Bareback Lung Job?

I've never heard the term either so you aren't alone. I'm thinking maybe he's just confused on the proper acronym

Bare Back lap joint?
