An adjective describing something that is disfigured in an extremly chaotic way. Similar to delapidated but with more emphasis on how mangled the object is.
When I lent my bike to phil, he brought it back majagulated!
A portmanteau of mangled and discombobulated, it can mean anything from the simple confusion of losing your keys, tripping over the dog and then pouring your coffee on your cereal, or ending up thinking you have 7 legs after a rave.
"Wow, Steve was sure mangulated last night, did you see him trying to have sex with that phone booth?"
