SIS
Smirk in Silence:
The act of putting on a straight face after putting someone in a spot.
Pulling someone's leg as a group where everyone acts normal in a scenario that is funny.
Used on social networks, chat rooms and forums..at least could be!
Totally loved getting on Spook's nerves acting as if I don't know him at the bar last night. Pulled a SIS.
