Tweek x Craig was just an episode to tip their hat to the fujoshi and yaoi fangirls here in America. Plus Trey seemed like he was dying to speak a lot more moonspeak.
Tweek x Craig is actually a big pairing, just under Style, and Kyman.
And seeing as Tweek hasn't had an episode in a very long time and Craig is the butt of the joke since The Startling. This was a perfect pairing to do.
The episode talked about how much the Chinese hate the Japanese (and vice verse)
Gay rights (the boys understanding what is gay, and how people become gay, and especially Craig's father accepting him)
PC/SJW/Liberals not treating gays equal.
It's beyond just the Tweek and Craig, that was just there to get people to freak out, and laugh.
And because South Park this season has been in full-drive on recurrent storylines (episodic in a way), they had to use minor characters that had a presence to the fanbase. And since Pip hasn't been seen since his supposed death, Damian has been reduced to a background character, and Butters has already had a lot of episodes, plus him being in slow cosby with the canadian, it just wouldn't make sense to push Cartman x Butters or Kenny x Butters.
