the hidden language of hugging

I first titled this post "the science of hugging," but there are no actual statistics or biological facts in this post. However, it is backed up by a lot of field study, so I still like to think that's like science.

Relevant side note:

There are different kinds of hugs.

I once had a guy inform me that every hug has a specific meaning. Depending on the way a girl hugged him, he could decipher if she was digging him. Basically, this is the hidden language of hugging, according to my friend:

1. The one arm over, one arm under.

Meaning: You're just friends.

2. The side hug.

Meaning: You're DEFINITELY just friends.

2. Girl's arms under, guy's arms over.

Meaning: She's more like a little sister to you.

3. Girl's arms over, guy's arms under.

Meaning: It's go time. In his words, her pretty face is "all up in your grill."

Do I agree?

Not entirely, actually. I would say #1 and #2 might be accurate, but maybe not the other two. The thing is, sometimes guys are tall. And then it's entirely unfeasible (and awkward) to go for method #4 without finding the nearest curb (or bench) (or trampoline) to stand on. (I take it back, I think a trampoline might cause facial bruising and I can't be responsible for your shenanigans.) 

Besides, I feel like every guy I've dated has had a specific preference between method 3 and method 4. I can see this becoming a thing: "Did he hug you?" "Yes." "And?" "Method 3." "Oooohh..."

My true feelings: you've got about 0.00005 nanoseconds to make this decision when it's hugging time. That's a lot of pressure and analyzing to put on something that allowed little-to-no prior planning. I tend to default to #3 and, noooo, that doesn't mean I want to be everyone's little sister. So gosh, let's not read too much into this, right?

I don't know, what do you think?

p.s. let's focus on the hugging meme in this post, because it's relevant and makes me laugh.
