I tend to do the Spock eyebrow raise quite a bit without thinking about it, to the point that people I know will ask if it’s on purpose.
I also will use “fascinating” and I tend to insert logical or illogical into sentences.
Worf’s “It is not funny, but I get it” is something I throw in as well.
If I’m in “Star Trek Mode” I’ll use various Klingon phrases, along with the Vulcan salute as greeting. My wife and I will at times text in Klingon. There’s other stuff as well, but not as common!
