Is your man sweating after you ask him a question? Maybe it’s because it’s actually hot out or he just finished a strenuous work out. Or maybe it’s because his pants are on fire because he’s a liar!

Communications experts there are telltale signs or certain words that a liar will use that are sure-fire signs he’s not telling the truth.

1. “But.” A biggie in the liar arsenal. He will even use it to say he’s not lying. “I know you think I am lying, but…” It’s another move to minimize what he is about to tell you.

2. “Would.” Ask him, “Did you have lunch with your ex?” and see if he squirms and answers with, “I would never do that to you.” He’s overcompensating.

3. “By the way…” It’s a phrase liars use to try to give lesser value to what they are about to say. “By the way, I’m going to hang with the boys tonight.”

4. “I think…” I think I left the bar at 2 a.m. OK. Either he was too inebriated to remember, or he is hiding something.
