Glomp Someone

This will show you how to pull off and receive the move that Otaku all over love: the Glomp!

Steps

Most importantly, get permission from the person you want to glomp. If someone else is glomping you, make sure they ask first.
To give a glomp: Get an appropriate distance away from the person. If in a crowded place, only go a foot or two away and skip the next step. For the ultimate glomp, give enough room for a running start.
Start running (but not too fast!).
Right before you reach the person, crouch slightly and jump up. Option 1: Mid-jump, wrap your legs around the person's waist and wrap your arms around their shoulders. Option 2: Land your jump in front of them and use the momentum to lean forward and hug them.
Cling to them, otherwise you will lose your grip and fall.
Step off/away from the person.
To Receive A Glomp: Stand with your feet firmly on the ground.
Tense you muscle to brace for the impact.
As the person glomping you hits, wrap your arms around their lower back and hold them up. You may have to step backwards to keep from falling.

Be cautious when doing this in costume or cosplay. You don't want anyone's costumes to get ripped or broken!
Be sure you know the person. You can really make them mad if they don't know you.
Be careful in crowded areas. If you fall, you could cause a domino affect and hurt bystanders.
Be careful not to do this near any stairs, escalators, or anything that could cause harm to the person you are glomping.
Always ask first!
