What Does MC Stand For? Its Slang Meaning, Rap Connection & More

What does MC mean?

“MC” is short for “Master of ceremonies.” A master of ceremonies traditionally acts as a host—for a formal event (like a wedding or gala), a public event (like a convention or conference), or an entertainment event (like a concert or open mic night). They’re usually in charge of energizing the crowd and ensuring the event runs smoothly. “Did you hear? That upcoming concert series just announced its MC!” “The talent show’s emcee went the extra mile to introduce every guest in a fun way. He was awesome!” “MC” can also be spelled “emcee.” They mean the same thing!

“MC” also stands for “Microphone controller” in rap and hip-hop culture. Performers of rap and hip-hop music are often called MCs—though in this context, “MC” stands for “microphone controller” or “mic checka.” Emceeing is often associated with live performances and lyrical content. Additionally, some rappers have the acronym MC in their stage name. “Mos Def is a crazy good MC. Maybe the best!” “Is there an MC you’d pay anything to see perform live?” Overall, the role and duties of an MC don't vary by gender; MCs mainly differ in terms of whether they're hosts or performers.

How does an MC differ from a rapper?

MCs and rappers are different but can sometimes overlap. While an MC can still refer to the general host of an event, the term became connected to rap and hip-hop culture in the 1970s. Originally, rap MCs were just hosts whose job was energizing the crowd. Over time, they leaned more into performance as vocalists who rhyme oversampling, scratching, and mixing tracks provided by a DJ. Rappers who perform live for audiences are also technically emceeing. You can refer to a rapper as an MC or emcee—but rappers can do more than just emcee. MCs are often associated with traditional hip-hop culture, while rappers are more mainstream performers. MCs don’t only exist in rap and hip-hop; garage, drum and bass, ragga, happy hardcore, and old-school rave music commonly have MCs too.

How to Use MC

Describe the host of an event you’re attending. If you’re going to an event with a master of ceremonies (or looking for one to host an event), use “MC” to refer to them. Similarly, you could use this acronym to praise an MC who was especially great—or criticize an MC you think dropped the ball. “Do you know anyone willing to be the MC for an open mic night?” “The MC at the wedding was so great! And she really made the afterparty feel fun.”

Discuss your favorite rappers with friends. You can also specifically refer to different rappers as MCs when you share artists you enjoy (or dislike)—or talk about rappers with MC in their stage name, like MC Lyte, Young MC, and MC Hammer. “Sorry, but no dance track will ever beat U Can’t Touch This. MC Hammer is timeless!” “Which MC is the greatest of all time in your book? I’m a big Eminem fan.”

Other Definitions of MC

It’ll be awesome!”

Definitely recommend it.” “Ooh, the MC’s backstory in this visual novel game is really interesting!! ????”

It’s so effective!”
