Recently had a mental breakdown and bought tickets to San Francisco to attend a brony convention/concert. £700+ from London. Not even a brony. Decided to say fuck it and go, needed a break. Easily the most fun I've had in years and have made friends for life. Thank you bronies.
@fesshole Presumably a ‘brony’ is a Northern Irish brownie(?)

@spacemagick @fesshole apparently it's made up of bro and pony and refers to male friends of "My little pony". You learn something new every day.
