The Irish/UK version of Jesus H. Christ in a Chicken Basket, this phrase is used in extreme situations of shock, surprise, annoyance, or disgust. The addition of a well placed f-bomb can, of course, up the ante considerably.
Helpful chap in bathroom: "I say, it appears that your penis is dripping a rather greenish looking slime."
You: "What?! JESUS H. FUCKING CHRIST ON A BIKE!!"
Very random display of disgust or surpise. Also used to emphasize a point being made, or to just humor your friends. First uttered by a by a dick football coach from a small town in Kansas.
Jesus H. Christ in a chicken basket!!! That was the shittiest block I've ever seen.
Guess what Chris? I got laid last night! "Well Jesus H. Christ in a chicken basket, it's about time."
