Sub Seating 

The "seating chart" that students assume when a teacher is absent and the substitute doesn't know the seating chart. This usually entails everyone sitting with their friends, which makes the class that much more loud and unmanageable.

Example 1
Hannah: Hey, Josh, guess what? Ms. Kelvin isn't here, we have a sub!
Josh: Aw, yeah, you know what that means! Sub seating!

Example 2
Sophie: Why are you sitting in your assigned seat? Come sit here, it's sub seating.

Sub-bitching 

Sub-tweeting is the act of tweeting about somebody without actually saying its about them..
So sub-bitching is bitching about someone, trying to make it more generalized even though its clearly aimed at one person

For example;
Roqueesha: "Some people really don't know how to do their make-up."

Lily: "Is she talking bout me??"

Breezy: "Yeah she's clearly sub-bitching"

sub-reddit suck-up 

Posts at the near bottom of any Reddit, 4Chan, etc. thread that are annoying in nature, to how they beg for a dying thread to continue.

That /vgg/ thread for Minecraft had honestly the most sub-reddit suck-up's I've seen. Honestly those guys were fucking begging for the thread to continue!
