Tar
1.) A black, goopy substance that was used in the past as punishment and harassment on people, and usually accompanied with being covered in chicken feathers. 
2.) A so-called "redneck" way to pronounce "tire". It is not redneckish though. This pronunciation is used in the lower Midwest, Appalachia, and Pennsylvania.
3.) An alternate pronunciation of "tower", usually said in the regions listed above.
After watching them cover the asshole in tar and feathers, we went to get my mom's tar's rotated, and then watched the world from the observation tar.
