With squish being the word for a platonic crush, a squish hug covers both the meaning of a tight, loving hug but also a hug with the wish to show a person love in a platonic, non-romantic way.
It's recommended not to say this to people before hugging them as it would confuse them due to their lack of knowledge about the word "squish" and its use. And they would mistake it for the other meaning of a squish hug, which is related to bosom hug.
(Squish her down:Sticking the dick in so hard that it hurt, just incase you didn't read it before)
Harley: Bitch why you walking like that? Did you grow a penis or some shit?
Ivy:No why the fuck would I grow a penis?
Harley: Just saying, so tell me before I make up more shit.
Ivy: Well my man fucked my pussy so hard last night, I could barley get out of bed
Harley: So he squished you down?
It’s like the scoop and sling but the opposite. After you cum inside a woman and in an attempt to impregnate her, you squish her lips together push them into the vagina
Imagine this: You're French kissing a girl. But instead of her lips, you're Frenching her chocolate horn blower. Now comes the squish, but only after 10 pounds of beans. More or less beans makes this nasty.
FRIJOLES!
Peetey Pablo: "Juan, Your mustache is running."
Juan: "That's because I was just French squishing."
