exdar

A specific form of radar, it is the uncanny ability to know the worst time to try and jump back into an ex's life and make them feel awkward.

1: "She totally just dumped me man"
2: "That sucks dude."
*ring ring*
2: "Who's that?"
1: "It's my ex-girlfriend."
2: "Whoa. Weird timing."
1: "I know! I swear she has exdar!"
