Having sex with someone that a member of your closest group of friends has previously had sex with; because of the close-knit friendship, your sex number does not increase. Just like actual recycling, this is good for the environment.
I had sex with Nick last night - he was as good as you said he was. I've officially participated in group recycling.

A Hell group is a type of Facebook group themed around a certain subject, used as a message board to "shitpost" content such as memes. The nature of these groups tend to be offensive, with people common ostracised for complaining about material being offensive, however these groups usually dissuade abuse and harassment. Popular topics mainly include, but are not limited to, video games and anime.
The most famous Hell group is Melee Hell, a Super Smash Bros. Melee group, and other popular groups are Waifu Hell, Initial D Hell and JoJo Hell. Food Hell is also a notable example of a non-video game or anime group.
"I was thinking of joining a Hell Group, is Melee Hell good?"

"Sure, but there's certainly a bit of drama there. I heard someone found a MH member trading nudes for amiibo on Craigslist and everyone flipped out over it."

A Facebook group that exists mainly for the purpose of tagging it in a discussion thread as a form of meme communication.

For example, one of the earliest Tag Groups on Facebook was, 'This isn't an airport, no need to announce your departure", which was born from the phenomenon of people who found it necessary to write a post about how they were mad and leaving a group. At which point, someone in the thread who knew about the tag group would put it on the discussion, prompting a laugh.

When you tag a group like that, Facebook puts the name of the group in bold, thus emphasizing its visual impact.

Therefore, users have added thousands and thousands of hilariously specific phrases as groups to the platform, giving the user lots of options of things to say in bold characters.

The bold name of the group is also a clickable link that takes you to the group, prompting more members and thus more taggers.

As mentioned before, the tag group mainly exists as a means for creating highlighted text in a discussion thread, however, some tag groups do become places of activity themselves.

For example, with "This is not an airport...", members who join the group will use it as a tag group, but then also screenshot hilarious examples of people rage-quitting other groups, and add it to the discussion timeline in the group for other members to enjoy and laugh at.

Not to be confused with 2M2B (capital letters, 2-methyl-2-butanol). 2m2b can form groups such as 2m2b-OH (2-methyl-2-butyl alcohol, C5H11OH, 2-methyl-2-butanol, 2m2bOH), 2m2b-Cl (2-methyl-2-butyl chloride), 2m2b-Br (2-methyl-2-butyl Bromide), 2m2b-F (2-methyl-2-butyl Fluoride), and 2m2b-I (2-methyl-2-butyl Iodide). In addition, it could also form 2m2b-MgCl (2-methyl-2-butyl magnesium chloride), an intermediate in grignard reactions (which are performed in diethyl ether or dibutyl ether).
Tony: I reacted 2m2b-MgCl in diethyl ether with methyl iodide to synthesize 2m2b-Me (2,2-DMB; 2,2-Dinethylbutane). I used the 2m2b- Group
