A Farkism for "When the S*** hits the fan", achieving noteriety in the thread What would happen if I were to boil some Poison Ivy leaves, and drink it like tea.? When one of the farkers posted this from Usenet: “The poison ivy oil (urushiol) wouldn't cause trouble in his throat, as a combining of that oil and the outer layer of the skin is necessary to form a complete antigen (allergen). He's likely to have trouble, however, when the oil hits his anus.” This also spawned a spate of photoshops using this phrase or a variant of it.
