scissors kissing 

Lesbian sex act where one woman rubs her girlie parts / vagina against another woman's girlie parts vagina.

This causes their legs to look like scissors (if you are lucky enough to actually witness this act)

Also see clam bumping or clam bumper

Two men getting it on is disgusting and wrong but two girls scissors kissing is wholesome and natural.
