The female "gunk" that leaks out of the vagina when 2 women with pubes scissor. The vagina lips act as the pasta outlay, the pubes resemble the meat, and the gloopy mess would be the cheese. Vegetarian lezagna occurs when the 2 women are clean shaven (no meat).
Dyke: Its dinner time babe. You ready for some veggie lezagna?
Lesbo lover: Sorry to burst your bubble, but I got a jungle of pubes down there right now. I'm horny as fuck also so do you mind if we have extra cheesy lezagna instead.
