A form of telepathy. When two males become such good friends that they subconciously know when one another needs to shit and both arrive at the bathroom together as shitting buddies.
I swear Tom and John have Toilepathy, for the third time this week i walked into the bathroom to find them shitting together.
When twins are known or to be known as telepaths. Having telepathic ability, and or some sort of weirdness going on when they are both aloof and afoot.
We were cooking in the kitchen and then i saw my friend open the door for his twin with out hearing a knock. They must be "Twinpathic".
