A slang used to define a rusty shitbox, originating from Romania.
It can be used for many models of cars. Examples are "skodar obosit" "toyotar obosit" "opelar obosit".
It can also be used to describe a slow driver of these cars.
I want to take this celicar obosit over but he keeps braking.
The celicar obosit arrived at my service shop today.
