In my opinion https://myreadingmanga.info/madobuchiya-nishin-chikuhyou-no-hanayome-orc-bride-eng/ this shit crazy
I personally love all of them but cheating/disloyalty vexes me but still I appreciate all of them.
In my opinion, this one http://www.mangago.me/read-manga/takaramono_wa_hako_no_naka/
Not going with the obvious shock horror stuff for me some of the worse would be anything like this: http://www.mangago.me/read-manga/koi_no_tsumeato/ absolutely unlikable protag, a pathetic bf, and an annoying ex. Lots of drama and little else. Bl triangles/harems tend to be pretty shit in general. It's why I get happy when a new uke comes like a wrecking ball and destroys it. I ~love~ it when a new uke appears, creates a second couple, and essentially puts a stop to the potential triangle.
This wasn't quite terrible per say but it left you with a very unsatisfied ending and just kinda makes you go "What? That's it???"

Can't believe I forgot that one. I second this.
This author is one of my favorites lol
It's easier to name the good ones lol
What kind of person wants to read bad yaoi tho lol, prepare to be vexed
I do that sometimes. It can't be healthy but I'll deliberately look for things I know will piss me off and read it all.
What is the worst yaoi manga
