Anyone know what's happening here? (Twitter gif that I don't understand)

To anyone who can't see it is a guy spraying what looks like liquid nitrogen into some athlete's shorts after he was injured.

1. I have never seen anything like that

It’s apparently a depiction of relieving teh butthurt.

4. I just remembered when I was a kid and broke my arm they sprayed something that made it

really cold, (looked like the picture but it was a spray can). It kind of numbed my arm so they could set it. Maybe this is something similar.

2. Liquid nitrogen would be mighty cold. I'd go with dry ice vapor or talcum powder. NT

6. See post 3. I have used this previously and know what it is.

3. Definitlely NOT liquid NITROGEN which would destroy tissue, but Clorethyl cold spray (Vapocoolant)

It does have a cryotherapeutic analgesic affect and limited studies suggest it is safe. Liquid nitrogen, on the other hand, burns tissue at -320F-- that is MINUS 320F!

5. Some sort of Cryotherapy freeze gun?

7. Most likely ethyl chloride, to cool and numb the skin:

First, it's important to note that not all cans are created equal. Some first aid sprays might contain a tincture of benzoin, a resin that makes a sticky surface on sweaty skin in order to better place bandages. Others might hold nothing more than cold water. A spritzer of H20 can go a long way to reinvigorate an overheated athlete.

However, the can of magic spray we’ve come to know and love for its injury-healing abilities typically contains one or more “skin refrigerants." These chemicals, such as ethyl chloride, act as a temporary anesthetic. They are a quick fix in their ability to numb an area for a few minutes, but do not provide any long-lasting relief.
