Dry day supporter

A dry day supporter is one who, going back to the days when football was watched standing up and without cover, is one who is quite happy to support the team a long as it is not raining. A dry day supporter then is someone who says he is a supporter of a club or team but whose loyalty is open to question. I cannot see any references to this on the Internet for some reason.

Trouble with a capital "T"

Trouble with a capital "T" was a favourite of my mother's. I was delighted when years after I had first heard it the Irish band Horslips came out with a song of the same title.

For the high jump

My mother (and sometimes my father) would warn me that I was for the high jump. Once I was in senior school or a little younger and aware of the high jump competition, it was always tempting to take it literally. It refers, of course, to punishment for doing wrong. It is apparently military slang originally, in connection with a horse and really refers to facing a difficulty of any sort.
