I'm not really sure what Atlanta Hawks game this clip comes from but more about the actions of one, Josh Smith that makes this video absolutely hilarious.
During a time-out, Josh Smith starts touching Mike Bibby on the shoulder for some reason and continue for a couple seconds.
Then all of a sudden, Bibby gives Smith the universal look of "stop touching me".
I think the term, "Pause...No Homo" was created for this clip.
