A lesch is that one drunk ass hole in the room that will be right next to you but still screaming. The one guy who gets really hammered but still be able to get everyone in the bar to love him.
A lesbian pedophile. A pedophile is usually a man, whereas a lesophile is a lesbian woman. Most lesbians are not lesophiles, the same way that most men (gay or straight) are not pedophiles.
My best friend's homeroom teacher was a lesophile; she gave the 8th grade girlsfree stuff and "special privileges" --nudge nudge, wink wink.
