I haven’t found a single dictionary definition that defines it in the way that you do. I’m sure they have slang words for ‘slut’ and someone might say, ‘That sheila is a slut’. But Sheila itself is simply the female version of ‘bloke’, and the average Australian woman wouldn’t find in it an insulting sexual connotation.
and you lived in Australia how long and when ???
and the average Aussie woman would slap your face if you called her a ‘Sheila’
Kid its an nasty insult...
I bet you believe everything written that Joe Biden says too...
Just because its written as ‘the truth’...
