Get the el Jackmug. A sex position where the woman puts a pumpkin on her head, while the man smacks her ass till it’s bright red and looks like a wild card. Also known as pumpkin fucking.
1- You what? What’s Jack O’smack?
2- Dude, haven’t you ever pumpkin fucked your girl? Fan-fucking-tastic!!!!

Get the Jack o’smackmug. When someone has previously called shotgun, and then gets out of the car at all, without calling seat-back. The person who wishes to obtain the position of shotgun shouts "shotgun hi-jack" and takes the shotgun position.
Joe's homey get's out of the car... like a fool he doesn't call seat back... Joe being the genius he is calls shotgun hi-jack and takes the shotgun position. Joe's homey returns to the car... and realizes he is a fool and sits in a non-shotgun position.
