the act of wedging a pipe bomb, molotov cocktail, or other homemade incendiary device into the anal cavity of a loyalist.
the Belfast Breakfast originated in the 1920s as an IRA torture and/or revenge method, not as wedging a pipebomb directly into the anal cavity, but rather dousing a loyalist's pants in whiskey and lighting, followed by uproarious drunken brogue laughter. It quickly evolved and spread to other guerrilla groups, and was even mentioned in Eli Roth's short animated series, "the Rotten Fruit."
The act of shooting someone in both elbows, knees, and ankles. The person shot will usually black out after the first couple shots, but after coming out of shock the pain will be unbearable. People who are given the belfast six pack usually deserve it.
