think bike

A slogan used by British road safety campaigners to try to reduce the number of motorcycle deaths caused by people riding motorcycles into cars, rather than trying to get motorcycle riders to ride more responsibly.

"I used to ride a motorbike but I had a few close calls and decided it was too dangerous. Think bike? Think maybe I'll stop being a fucktard and get a car before I end up with my handlebars through my sternum."

Thinking-Cap

When your dumb ass is so dumb that you need to wear a helmet when doing normal activities such as riding the short bus or sleeping. Also, randomly dropping face first out of nowhere may be a side effect.

Dave's dumb ass fell straight out of his chair the other night and ate carpet, luckily he was wearing his thinking-cap.
