When a guy you have been bumping uglies with, on and off for a few months, gives you the cold shoulder, not returning texts, gets a proper "girlfriend" and generally acts like a douchebag. You move on, months go by, but as soon as other guys start sniffing around, douchebag gets back in touch - having some kind of dixth sense - like his tallywhacker knows when there is competition......
Girl 1: "FFS, I just gotta txt from douchebag - I aint from him in months. Typical, as soon as there are other guys on the scene, he wants to tap this ass again......"
Girl 2: "What ya gonna do?"
Girl 1: "Dunno, its like he's got a dixth sense or somat"
*texts douchebag anyway*
Similar to VSP, a specific form of ESP where a woman can tell the size of a man's dick just by talking to him.
I'm telling you my Dixth Sense has never failed.. and trust me I have been with a lotta guys!
