A girl who acts like a lesbian until she finds a boyfriend. Not to be confused with actual lesbians, safety lesbians may:
A) use sexual preference as an excuse for a chronic lack of boyfriends,
B) attract guys with the promise of a threesome,
C) muff dive until 'the right guy' comes along.
Maria) "Stacey thinks we should threeway with Jake."
Maude) "Be careful, she might just be a safety lesbian."
Claire) "So you're a lesbian?"
Janet) "Yeah, until the right guy comes along."
Claire) "Pfft, safety lesbian..."
