Shivelights 

Sharp rays of bright sunshine that pierce the canopy of a wood or forest. The word possibly owes part of its origin to shiv slang for a knife which in turn is derived from the Romany word chiv meaning a blade

Those shivelights are so bright they hurt my eyes

Shitelight 

The slang term for the series of books about a girl struggling to choose a boyfriend. Her choices are: a pedophilic guy who wants to kill her and a werewolf who doubles as a Native American stereotype.
Possibly the worst books ever written.

I read Shitelight at the weekend just to see if it was any good. I regret that wasted time.
