A strong, independent woman/girl, who is proud of her jeep and her fellow jeep family. She builds other up instead of breaking them down. She believes in herself and her ability to stand on her own two feet. She is kind and giving, but don't get on her bad side, you won't like it.
Jeesh means army. The confusion is in the pronunciation. If you pronounce it like it is spelled in English, then it does indeed mean "piss". However the correct way to say it is more like "jay-eesh".
