Guys, why do you squeeze a girl when you hug her?

is there any meaning behind a squeeze hug given by a guy?
for exemple after talking to a girl for like 40 minutes (for the first ime, i mean you just met), and you squeeze hug her.
Thank you in advance :)
Feel protective over her
Want her to feel safe
That's the way you hug everybody
other (please comment your suggestion :) )
