look up any word, like hipster:
 
1.
The act of grab the left side of you ball sack and then the right side and pull them apart like a bat wing of sorts. Then you yell horny pterodactyl and run around the room repeatedly proclaiming CA CA CAW CAW. i.e. (like a horny pterodactyl) this is most effective when while in deep eye contact with a female. (Post quoits is best for obvious reasons)
I gave her the horny pterodactyl and she thought i was so funny she maried me.
