Fixie’s and people who call fixed gear bikes fixie’s. Realise the trend is all but dead but it needs to completely disappear so I can just get on with riding my fixed gear bike in peace
It’s just a contraction. As is “bike”, which you appear to be arbitrarily perfectly happy with. (Along with omitting pronouns and full stops, and inserting wayward apostrophes, but I digress.)
I hate these threads, because one of the things that riles me is people getting all pompous and fussy about other people using words in a perfectly legitimate fashion. God help us if you lot ran the world and we had to use the most tediously literal devices possible for everything: we’d end up with a literary culture whose apogee was the script for a self-service checkout.
