look up any word, like dirty sanchez:
 
1.
The act of attempting to instill fear into someones mind by sharply turning your head only and staring into their eyes with a sharp look, only to fail due to not being threatening or deadly in anyway. Usually attempted by fat, overweight people, or by a man by the name of Johnathan Diaz.

Reference to Steven Seagals film cover of "Today You Die"
"I bumped into someone earlier and he tried to give me the Seagal Staredown. Was I supposed to feel threatened?"
