What for you is the biggest turn off in someone...
 

..pet hates/bad habits etc or just generally irritating..?..

their husband:joker:

My other half is perfection, he has no irritating habits :xyxwave:

he as you well trained:shocked::joker:

I think you will find it is the other way round :hmph:

Smoking

Swearing, spitting, people who eat with their mouths open, people who dont cover their mouths/nose when sneezing or coughing.

This ^ :love:

..and another this ^...hmmm, I hope our partners aren't one and the same person, being married to a bigamist really would be a bit of a turn off for me...

:laugh2:

Mean Spirited, Arrogant types.

Bad manners

Being two-faced,deliberately causing bother for others actions and not giving others a fair chance.
As if some people are always wrong and never right, while not seeing the faults in ourselves and those we like too.

Bad breath

For me it's bad breath,nose picking, two facedness and arrogance.

this is up there with the biggest turn offs

Agree with the bad breath^^^ and also just bad hygiene in general, soap, water and washing powder doesn't cost a lot.
