Whats the best ever scifi universe curse word equivalent to the F-bomb?

Im tryin to remember the most emotionally equivalent word to “fuck” that basically means spacing someone.

Somewhere in the volumes of scifi that i have consumed, there was a story told where folks used a word that meant “ejecting that mofo into the void cause fuck ‘em” and the way they used that word was so satisfying (granted not a perfect parallel, but damn close)

I was trying to insult someone the other day and really needed whatever this word is. Yeah it was an overly elaborate insult, but i wasnt wearing a fedora. It was a friendly insult to a person who would have probably appreciated the reference if i could have pulled it outta my ass.

What are your favorite and most vile scifi swear words?
