A friendly saying of hi there.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

I know your verifying if this is correct or not so if you could accept that would be nice also I appreciate you for sorting the dictionary ❤️

You missed a space somewhere. I think you were spelling “hi there” or “hit here”.

Code for I’m gay/lesbian, homosexual greeting originating during the 1960s, not used frequently today, it was used because it sounds like a normal greeting, and was non suspicious only those in the community new it’s hidden implications, this phrase is actually referenced in the movie Dr. Strangelove (How I Learned to Stop Worrying and Love the Bomb) as it is pictured on one the missiles, it is shown beside a missile which says Dear John a reference to WWII break up letters

Like everything else on Urban Dictionary, ”there” means ”cunt” or ”vagina”. ”Hi there” is an idiomatic expression for ”You f*cking cunt!”
