Trolling does not mean just making rude remarks: Shouting swear words at someone doesn't count as trolling; it's just flaming, and isn't funny. Spam isn't trolling either; it pisses people off, but it's lame.
The definition of aggravated is something that intensifies or worsens something like a condition or circumstance. Carrying a gun while committing a burglary is an example of aggravated burglary and carries with it a more severe penalty. Aggravated is defined as something was made more intense or acute.
A state offense meeting the federal definition of a crime of violence where the sentence imposed regardless of any suspension of imposition or execution of sentence of one year or more will meet the definition of aggravated felony under 101(a)(43)(F) INA.
