A condition, related to bat wing, that is the result of a male's excessive exposure to humidity in the genital region. Less common--but more dangerous--than bat wing, this condition is when not only one, but both sides of the scrotum adhere to a leg. This double bat wing conjures up memories of the extinct dinosaur for which it is named-- the pterodactyl.
"I was stuck riding bitch in the back seat for 2 hours, and when I finally got out I had some vicious pterodactyl."
