Please define "dirty old man"

Dirty old men are those who openly flirt with people who are paid to be nice to them, like nurses, waitresses, airline stewardesses and cashiers. Those who feel women's bodies are free to be pinched and groped. Those who never miss an opportunity for an unwanted sexual joke or inuendo.

Yes, but not harassing others like many do here. There’s a huge difference.

Often they push this on unwilling others. That's the line. Don't be that guy.

Showing the youngsters how its done...

Don't be jumping in muddy puddles and take your shoes off before you walk on the clean carpets.

Thinking it over a dirty old man is someone like me who would date a gal thats 20 or older. Who couldnt guarantee the world but could guarantee i could rock their world.

"Dirty old man" is a post-Depression Era expression that was used by women of the socially elite during the 1930s to describe any man who was older than her daughter who would be interested in her baby girl, a girl who could be a 25 to 30 year old unwed young woman who still lived at home with her parents, but attended social functions with them looking for Mister Right.

The "dirty" part is in reference to rich older women looking down on less-than-rich younger men who would dare to attempt to worm his way into their social circles through his apparent connection with the daughter.

If they grossly perv on everyone in sight especially super young girls its cringy eh?

old is synonymous with decay, natural law say they are wrong and anti nature.

The term "dirty old man" refers to an adult male who is sexually interested in girls. There is no age criteria that defines a man as being a dirty 'old' versus a dirty 'young' man. The term originated in Great Britain and spoke to the ultra-conservative Victorian bias that Brits once put on anything sexual.
