To Hit the high "C" is to make the high pitched noise emitted by a man who has just been injured in the genital area. It's a note easily achieved by
choir boys and opera singers, but most men will only ever manage to attain such highs when they've sustained a blow to the bollocks.
To induce this noise in a gentleman, use
reasonable force when striking the area. Note-
REASONABLE force. Excessive force will result in no sound, as the note emitted will be too high for even dogs to hear, or he'll be unconscious, which is no fun for anyone.
Example:
"I accidentally
elbowed Finn when I went to grab my handbag off the floor. He really hit the high "c", it was hard not to laugh"
"Ferdinand with a very good interception cleanly takes the ball away from
Cissé. Now
Gerrard comes dancing in like a fairy and oh! It's a kick to the balls from Ferdinand! And there's Gerrard, on his knees, having just hit the high "c""
