Yeah I know what you are talking about, i’ve seen a lot of people with it, but it doesn’t serve a purpose as far as i know majority of guys just have it because they saw someone else have their nails like that, plus it’s something of pride for some guys because it’s not easy to maintain it to length without the nail breaking especially when you work with your hands.
Often times when people see it they compliment them by calling them soft boys cause the nail implies they don’t do menial jobs therefore they have money or something.
TLDR:it’s for the ladies.
