Dirty fingernails, bad hygiene and eating loudly are deemed to be the most common turn-offs among single women, according to a controversial new thread.

An online debate was sparked after a woman asked a popular Facebook group what gives them 'the ick'. 

Hundreds responded by listing their turn-offs in men based on how they behave rather than looks. 

Surprisingly filthy fingernails and a lack of hand hygiene disgusted both men and women the most. 

Singles flooded the comments section offering their opinions and personal experiences. 

Other turn-offs included road rage, being rude to waiters, bad hygiene, eating loudly and being selfish. 

One woman said she's completely disgusted when a man 'puts their finger in their ears'. 

'I can't believe some people think this is okay to do when you are in conversation with someone,' she wrote. 

Another added: 'This is probably unpopular opinion, but men so obsessed with football that it consumes them!'

A third doesn't appreciate men who 'lack basic manners' or a rude towards others.
