stubblebump 

the red, prickly, swollen nodule found on the surface of one's scalp. stubblebumps can be spotted in anime shows; however, they exist in real life, but are often concealed under snug-fitting tophats.

Wendell had to duck at the threshold to prevent from bashing his stubblebump against the doorframe.

Stumblebumbling 

The act of walking around a city or town, out of pure amusement or lack of anything else to do.
