my dp has epilepsy and watches eastenders all the time, so am sure if he found it offensive he would have said something to me about it.
personally its not something that i would say but i have never heard it before reading this op.
also arent most words, excluding words like ngger, spzz etc only offensive because of the meaning that is placed on them by others who think that they may offend certain groups of people. i.e. epi, dp often tells me 'there is no need to have a fit about it' he has never said epi but then as i said earlier its not something that i have heard before.
also the word gay is used here a lot as 'thats so gay' not in a nasty way its a phrase that people use. i use myself sometimes, although i dont mean to, its just part of our slang and easy to pick up without realising the connotations and isnt intentionally aimed at anyone. my sister recently said it at her workplace infront of her gay best friend realising what she said she apologised and said 'i shouldnt that it might offend some people' some one who is not gay or lesbian said 'yes you are right it will' very sternly to her, her gay bestfriend replied 'why, that was gay'
my friend who is black once told me that he has no idea wether he is meant to be black, coloured etc. he found coloured the most offensive as he is not coloured he is black as far he is concerned he is more offended that people are making such a fuss about what term they should use to describe his skin colour.
imo words only become offensive when people start making a huge fuss about them.
