look up any word, like cleveland steamer:
The sixth sense that tells you a woman is homosexual.
She looked hot from across the room, but when I approached her my lesdar went off.

The ability/gift to detect lesbianism in other people. Similar to gaydar, but specifically for the females.
She's wearing flannel AND Birkenstocks? My lesdar is going haywire!
