Silarious 

Sad, yet hilarious.

I.E.- Trump tweeting a feud with cable hosts (as president) is funny, but the fact it is real is rather sad.

Trump's unhinged press conference was silarious.

Silarious

Silarious (adjective): Describing a situation so serious you should stop laughing, yet so funny you can’t.

Someone jumps a fence to show off, catches their trousers, flips so awkwardly it looks hilarious, lands badly and breaks their arm. Everyone knows the injury is serious, but they still can’t stop laughing. That’s silarious.

silicious 

Delicious, yet creepy. Suggestive tones that if not welcome, are clearly sexual harassment.

His silicious comments, though very creepy, were somewhat arousing to her.

A reply to a post online that is so overused it is no longer funny, hence the intense sarcasm in both words
