Bad marks at school?

Usage examples of zits.

English zits from Heathrow on, and I was developing a hunchy slouch, the way tall girls get, from sneaking past mirrors.

My friend with zits pointed to the right, where the road bent to the left before disappearing.

The guy who took my money had more zits on his head than brain cells in it.

But it made him feel like a prototypical adolescent: a reeking gloom of zits and tit mags.
