Kibosh

As in, to put the kibosh on. Not my favourite word but an interesting one, mainly because the origin of this word is largely unknown. There are a few theories as to it's origin, but none have been proven.

Anyway, I'm considering putting the kibosh on my aspirations of going in the City 2 Bay this year, not because I'm injured or because I wouldn't make the PB, but because of constraints on time and money. I may go past the course on my way into uni to watch the leaders go by. I probably would have time to go in the race, but by the time I've finished, cooled down, had a shower and travelled back into uni, most of the day would be gone. The chief financial officer has also expressed concerns about the cost of entry, although I should be able to find $20 somewhere. I'll think about it.

Here is the Oxford definition of kibosh.
