Puzzling out katakana dialogue

[lynxian]

I know that most of it's hidden behind the box in front, but I can't even figure out what the visible parts are trying to say. I have a feeling that they're all phrases used on forums (I found quite a few with キョエアー) or something similar. For context, a bunch of students are freaking out upon realizing they're trapped in the classroom with a poisonous snake.

From what I could scrounge up online...
キョエアア = こわい?
ブロベア - all I could find was something about a word combining "bull" and "bear" and how it refers to strength/weakness. Might be a condensed way of saying "brown bear" (found an instance of スノ娘 being abbreviated as スノムス).
バコブチュケペ - I'm not even sure if the ケ here is correct...
ブチ = same as in ブチ壊す/ブチ殺す or emphasizes a verb/phrase like in ぶっ殺す?
ペペ - a name? Part of a word?

Help would be greatly appreciated.

They all sound gibberish to me.
