KSDK - It's a day of warm and not-so-warm embraces, a day of awkward physical contact, and a day of affection and titillation. That's right, ladies and gentlemen: it's National Hug Day 2014.

Here's are 17 types of hugs that we've seen:

THE AWKWARD HUG

THE CUTE ANIMAL HUG

THE (LITERAL) BEAR HUG

THE ENVIRONMENTAL HUG

And here you were, thinking "tree-hugger" was not a literal term...

THE MAHMOUD AHMADINEJAD HUG

Despite being a dictator, the dude's a hugger.

No...seriously, he just loves to hug.

Oh Mahmoud, you softie...

THE VOLUNTARY CARROT TOP HUG

Nice job, Joey Fatone. Take one for the team! #respect

THE HUG BETWEEN THE TWO MOST POWERFUL PEOPLE IN THE WORLD

THE HOLY HUG

THE ROYAL HUG

THE LONG-AWAITED HUG

THE HUSBAND/WIFE HUG

THE TAYLOR SWIFT HUG

You better not talk to her boyfriend, though.

THE MAN/DOG HUG

THE AWKWARD DAD HUG

THE LOVING MOM HUG

THE MAN HUG BETWEEN BROTHERS

And if you've got nobody to hug... (hey, there's no shame in that)

THE SELF HUG

It's the hug version of a #selfie.
