Noun: a person who loves musical theatre to the point of obsession over musicals and showtunes.
Musical theatre kids will likely stream and download showtunes more often than 'regular music' or songs by popular artists. They will often make musical references in everyday conversations, whether or not the person they are talking to recognizes it. They spent a good amount of time memorizing showtunes from their favorite musicals, and nothing will stop them from singing along once they do so. One must be careful when approaching a musical theatre kid, for even the most offhand comment can spark an immediate reaction that will usually comprise of a full performance of the show referenced. Many musical theatre kids find themselves constantly discovering new musicals, resulting in the pain they feel when being forced to choose their favorite. Common traits musical theatre kids share are creativity, determination, and freedom of expression.

Get the Musical Theatre Kid mug.
You're not a musical theatre kid if you aren't sure whether or not you'll going to broadway. You are always at rehearsal and can never hang out with anyone. Haha jk, if you are a true musical theatre kid, your only friends are musical theatre kids. You cannot sport for your life. You are the one at the party that doesn't know that popular rap song because you only listen to musical theatre songs. Haha tricked you again; you don't go to parties, you're always at rehersal.

You take Singing, Dancing and Acting lessons and pay way to much for all three.
Hey you want to come watch football sometime.

No sorry I don't sport, I'm a Musical Theatre Kid
