A beautiful leggy blonde dish, suitable wife material. Drinks like a sailor but is still a class act. A real catch!

I caught myself a real Marstar!

MarStarBro 

An asshole who harasses EXE fans. He also uses his age and "mental health" as an excuse when he would rush his mod, like how Milk was so mid cuz he rushed it.

MaSTAR Media 

The act of rotoscoping (tracing) in animation without giving credit.

The popularity of a particular YouTuber (MaSTAR Media) caused those to shame animators using the same technique as him.

Generally, you simply cut this down to MaSTAR.

"This is such a MaSTAR Media"

"Whatta MaSTAR!"

Marstyr

An astronaut (say a NASA astronaut from the ongoing Curiosity project or any such in the future) who dies on / on his way to / on his way back from / because of something related to his/her journey to/from MARS, which is for the sake of Science/Astronomy/humanity.

Of course, I doubt about any need to elucidate it. Play with the words 'Mars' and 'martyr' is all it is. This is a word of the future!
Hope there won’t be any Marstyrs :)

This new pioneering NASA project is gonna create a lot of Marstyrs because of its deadly mission conditions.

A person who enthusiastically loves the Marvel Cinematic Universe and is unable to accept any of its faults.

Person 2: "He's such a Marvtard!"
