Batshit Insane is a level of crazy that many people, including myself, experience, either constantly or momentarily.

In order to be truly Batshit Insane, you must abandon all rational thought, and let your Bizzaro instincts take over. You must clear your mind of all those pesky morals, too. Trust me, it's very, very rewarding.

Now that's the monetary tyep, the permenant type is best explained through example:
GOOD Batshit Insane:
-Me
-You
-The existence of UltraNeko
BAD Batshit Insane:
-Transformers Fans
-Star Trek fans
-Serial killers
-Serial rapists
-Serial robbers
-Serial killer-robber-rapists
-Those who doubt UltraNeko
-Alan Moore
Good:

-So, you're telling me that there's someone in this world who is a woman, loves video games, is funny, and seems like you could talk to her on multiple levels?
-Yep.
-That's Batshit Insane!

Bad:
Random British person: Did you hear they're making a Watchmen movie?
Alan Moore: WHAT?!?!? I OUGHTTA FUCK THOSE FUCKERS RIGHT UP THIER FUCKHOELS TILL THEY CUM BLOOD AND THEN EAT THIER INTESTINES!!!!!
Random British Person: Now THAT GUY is Batshit Insane.
