Double meaning Tildes post tag writing prompt

I was reading this post about the Tildes hierarchical tag system and it got me thinking about possible tags with double meanings.

For example, the gooning tag could be interpreted in a sexual way, or interpreted as the act of being a goon/villain. To clear up the misunderstanding, you could make a gooning.baddies tag, but that also has a double meaning.

What are some tags that could be used for serious topics that can have a less serious interpretation?
