Ex-"friends" or "cliques" that later on become a running joke? :p
My brother and i knew this guy/group that i hung out with a lot for a while when i first started smoking weed... (you can only imagine lol..), they were disgusting people and one of them pulled a really sly move while we were on vacation once, (he was watching my house for us, and he drove my truck without permission and lied about it later) and now me and my brother and my real friends (who are good guys) all make fun of them extensively, rip on them for how lame and ghey they all were, and call them scuz, + many other quite gross things that guys come up with. We actually formed a specific label for them and their type of people, "ScuzzBerries". It's hilarious...
