Nigger Trigger

Make sure you push the nigger trigger when you take the picture of a brother, otherwise the picture will be ruined.

Trigger Happy T.V. 

British TV show which American's constantly refer to as "The British version of Jackass", even though the original release date of 14/01/2000 precedes the the original release date of Jackass by almost 8 months, and the quality of humour is staggeringly higher due to the genius that is Dom Joly.

British person: "If you like your comedy shows, you should give Trigger Happy T.V. a watch...it's one of the funniest programmes ever."

American: "ye dude isnt that totally like the british version of jackass?"

British person: "Stupid yank."

Trigger 

A strong emotional reaction set off by a set of words or image that reminds a person of a traumatic event. Used often in the Self Injury community to describe something that may cause a person to relapse into a cutting, bullimic, or other self injuring state.

That poem mentions rape and self mutilation. It could trigger.
