>Notion:
In some computer programming and search engines, the ‘!’ symbol is used to denote ‘not.’ This can and should be applied elsewhere. As in writing “I enjoy old Rage Against the Machine but !rap-core.” Or it is especially dorky when used in online profiles to highlight specific disinterests:

Name: Erik Erickson

Interests:

Kittens

!Murder

See? I am especially not a fan of murder.

Usually.
