sub4sub 

A popular phrase used on YouTube. When you ask someone for a sub4sub, you subscribe them, and they subscribe you, in result, both youtubers gain a subscription. Unfortunately, a large amount of youtubers that do this are kids who have awful videos or (god forbid) no videos. Those who have awful videos just want attention. Those who have no videos look like complete idiots each time someone sub4subs them, looking more and more like a chode. They have yet to realize this. It is rare when a person with good videos asks for a sub4sub, because they usually do not need it. These Sub4Sub whores are usually found on Fred's channel.

StupidKid1: Hey dude wanna sub4sub?!
RegularUser2: No, your videos are horrible, and I don't need to sink to your level to gain subscriptions.

StupidKid2: SUUUUB4444SUUUUBBB?!
RegularUser2: You have no videos. Why would I subscribe to someone who doesn't have any videos? You are a failure.

Sub2Sub 

A shitty way to gain subscribers on YouTube without much effort, its highly possible that the person who subscribed to you will later unsubscribe to you. Don't do this its actually fuckin’ horrible. This is about the only thing less effective than being a sound cloud rapper. Its also so fuckin’ long.

Subsubarbs

A place that's sort of out of the way, and doesn't have very good cell phone reception. It's not exactly rural though, most of the people only have about an acre of land, only about half of the people living in any given subsuburban neighborhood are zoned for farm animals, and very few actually own them (though there not that uncommon), or do any farming. Still, it's not really suburban. There's no real planning to the housing, and it's a ten minute to any stores and restraunts.

Joseph lives in the subsubarbs, so don't surprised if you see a horse.
