AstroTerps 

The University of Maryland Astronomical Society - - A group of students at the University of Maryland who are either astronomy majors, or interested in the field of astronomy. The group meets every so often to discuss recent news in astronomy and/or space flight and is open to all who are interested.

Student 1: "Hey, is there a group on campus dedicated to astronomy?"
Student 2: "Yeah, the AstroTerps, go to CSS and ask around about joining, anyone who's interested can be a member."

astroTERFing 

The use – by men – of fake social media accounts that pose as feminist women, to object to the rights of trans women to be recognized as women. See also: Astroturfing, TERF.

Most of the people defending this anti-trans bigot are puppet accounts with stock photos of women for avatars. Literal fake women supporting transphobia: typical astroTERFing!

Astroterf 

The combination of astroturf and TERF. The spamming of feminism-themed transphobic opinions in media at a scale disproportional to actual opinion.

With recent polls suggesting that more women are accepting of trans women than not, what we see on Twitter every day may as well be astroterf.

Astroderping 

When a company uses fake accounts to make it seem like regular people support their corporate political positions but the people posting are too stupid not to get caught.

Did you see all the fools astroderping for Amazon recently? Similar to astroturfing except the people posting are too dumb to get away with it.
