When a girl likes to unleash a giant queef onto your penis while you are pumping the vagina.
Joe: What the fuck is wrong with you?
Brittany: What are you talking about?
Joe: Are you a queefosaur?
Brittany: What?
Joe: You unleashed a giant queef onto my cock.
A cancer of the vagina that causes uncontrollable queefage. This has no cure, and causes many women to become sterile or never have boyfriends. Their queefs are generally more potent than others, and fire out queef nuggets like a MP-40. The only way for temporary relief comes with the Queef-B-Gone cream.
I got Queeftasticular Cancer from Aleta and I eat tons of queefnuggets nowadays.
