A person's eyes when that person is lying because the eyes take on that "look" that can only found in lying eyes (regardless of what is coming out of their mouth). Most people have two, some people only have one. Some people, like pathological liars, have none at all. You can't hide lieballs. They'll always give you away. Easiest to notice on someone you know very well.
I knew he was cheating. When I asked Steve what was going on, he said that nothing was wrong, but his lieballs gave him away. Two days later he admitted that he started staring dating someone else two weeks ago. I knew it! Bastard.

When confronting the person, this is a typcial phrase, "don't try to fool me, your lieballs are giving you away."
