"That big mama can go five miles an hour faster on her bike now that she got herself that NASCAR facelift."
"NASCAR Facelift" describes the tightly-pulled-back hair style favored by lesser-educated women in the lower socio-economic class.
If that big mama's NASCAR Facelift was any tighter, she'd have a permanent grin."
