cat clocking

When you catch an individual looking at you and they immediately look away only to look back at you soon after. A phrase derived from the old fashion cat clocks that would move their eyes from side to side as the seconds went by.

Dennis: " Have you seen who's here at the party?"
Alex: " Yeah man, looks like Torran made it after all"
Dennis: " You think he knows you are here?"
Alex : "Of course he knows I'm here, he's been cat clocking me since I got here. Acting like he hasn't seen me" "He knows he owes me money"
