During the middle of Season 6, Butters is replaced by Tweek as Kenny's replacement. Therefore, Tweek is the reason Butters has his Professor Chaos form.
Butters checks up with Stan, Cartman, and Kyle while they are building a snowman with Tweek and asks how they like him as the new fourth friend, to which Stan responds by saying "He's certainly no Kenny, but he's still better than you Butters" and then Butters wishes Tweek luck as Kenny's replacement before walking off.
Butters also encouraged Tweek (along with Craig) to join his "Wieners Out" movement in "Douche and a Danish" and tells him and Craig that just because they're gay doesn't mean that girls will look down upon them.
There are very few fanfictions that include this pairing, mainly due to Tweek's canonized relationship with Craig overshadowing any other pairings involving him.
