Strangle-choke

DSM-IV 1) A condition wherein, a person who is an expert at a task, is forced to watch or teach a person who is horrible at the task move really really REALLY slowly. E.G., a luddite using a computer mouse for the first time. The person who is adroit at the task, slowly goes crazy watching the inept person trying to complete this simple thing, and wants to alternately strangle and choke them...but you'd never do such a thing. 2) When walking in a large city, with many pedestrians who are moving slowly, and are not self-aware, that block your path, don't walk straight, stop to take pictures of buildings, et cetera...and you...the fast walker, want to strangle and or choke them and move on...but you'd of course never do such a thing. 3) Anytime you're so pissed at someone or a pet, and you fantasize about strangling and choking them...even though you are so anti-violence that you're a vegan and a card carrying member of Amnesty International
