RattyMouse 

1. In some South American countries where small rodens are common, people struggle to differenciate between a mouse and a rat, so they use the name "RattyMouse" to describe both.
2. The description of a loveable partner or friend that has rodent like feature.

Jose: Damn man, who ate the rest of my chicken I saved last night, I was going to have it for breakfast?
Enrique: It wasn't me amigo, I saw a "RattyMouse" eating it last night, but I was too drunk on tequilla to do anything.
Jose: You drunk fool! Now I will be hungry all day because I didn't get my breakfast. It's your fault.
Enrique: I hate you!
