Japanese: What do "Gamaji" and "Gamaji" mean?

I think the difference between "majika" and "majikayo" is explained as follows:

マジ (まじ), pronounced "maji", is used to describe the verb, meaning "serious; True; " Seriously "is the abbreviation of" true face ".

「マジか」(majika)？ Is "マジかよ」(majikayo) an interrogative modal particle added after マジ? かよ means "Really?" Or "Is it true? "Sometimes, it can be simply omitted as" マジ "(rising tone means interrogative tone), which is equivalent to" should ". Generally used in young people's spoken language, disrespectful, can not be used in formal occasions.

For example:

このニュースまじかよ。 Is this news true?

Besides, マジ can also be used in declarative sentences or exclamatory sentences to emphasize "really (very) ...".

For example:

マジでしぃ delicious! It is really delicious!
