ununennium 

Pronounced: /ˌju nəˈnɛniəm/
A temporary systematic name for the hypothetical chemical element with the atomic number 119 and the symbol Uue, assigned by IUPAC. Ununennium is expected to be the first element in the eighth period of the periodic table and a member of the alkali metal group. Its properties have not been observed and are currently predicted only through theoretical models. If discovered and confirmed, it will receive a permanent name.

• Scientists continue to theorize about the potential chemical behavior of ununennium.
• If ununennium is successfully synthesized, it will extend the periodic table into a new period.

Unununium 

Long ass element that no one gives a dump about. Goes along with Ununquadium, another useless element.

Guy 1: "Hey, do you know about unununium???"
Guy 2: "Nope, cause i don't give a dump about it!"

Ununpentium 

The old name for Moscovium, the 115th element of the periodic table. Its symbol was Uup. Its name was probably made up from latin word for one, and the greek word for five (I think, I may be wrong.)

Ununpentium was changed to Moscovium.

Cheeks 

An Irish phrase meaning shit, derived from ass
(Not to be confused with the literal description of one's buttocks)

"Did you hear the song Aylek$ dropped?"
"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."
