A discreet way of saying and/or pointing out a lesbian to another, whether it be for laughs or just a general notification.
NOTE: Using your actual elbow to point out the previously mentioned lesbo makes the strategy even more flawless because if any bystanders or the lesbian hears you and looks over they think your just talking about your elbow.
Lesbo= L Bo = Elbow
"Yo man check out that elbow!! haha "
"Dam i wish my mustache was that badass"
