what's the worst about being a boxer? poking your nose with the gloves...

I am a native spanish speaker, and this was a way that I could find in English to still have some sense and some humour on it, I've never hear the last straw in a sentence, so I would give my opinion in that, since colmo, you are refering as something bad about it, at least we use colmo like that in México, cheers buddy
