A thread of f(x) songs with clever, quirky, creepy and weird themes and lyrics.

Shadow - A song told in the perspective of a stalker who obsessively follows her crush around under the delusion that she's on a date with him. Everything from the instrumental in the beginning to the lyrics just scream creepy.

Rum Pum Pum Pum - The girls compare themselves to a wisdom tooth in this song. I mean the first line of the song is "hello you probably heard of me atleast once, you wisdom tooth". Also f(x) did I'm different I'm not like the other girls first. They walked so ITZY could run.

Pretty Girl - Told through the perspective of a wicked and ugly protagonist who is jealous of pretty girls and casts a spell on them so that they they all look the same. She even calls herself the Wicked Witch of the West.

Step - A continuation of Pretty Girl. The wicked witch has now transformed into a self-assured and mature woman who has come to love herself. But she's still different, she's not like the other girls. They wear high heels she wears sneakers.

Airplane - This song likens the feeling of entering a relationship to an airplane taking flight, having worries about the possibility that it might crash but getting on board anyway.

Toy - This time they're calling out a man who manipulates and plays with girls like they're a toy, calling him a collector. Towards the end they ask "hey, what do you wanna get this time Mr. Collector?"

No More - Originally supposed to be an Ariana Grande song called Boyfriend Material, No More is the counterpart to Toy. It talks about a fox-like friend who changes her personality for every new guy she meets. It also has the iconic "your new boyfriend's a church oppa, right?"

NU ABO - The title of the song being a wordplay meaning "new blood type" with the blood types being A B O. It basically implies that they're fresh blood in Kpop.

Sweet Witches - Here f(x) call themselves sweet witches and compare their love with a medicine they have concocted.

ME+U - The lyrics to this one are pretty self-explanatory. It's about a girl crushing, more like thirsting after her teacher.

Red Light - It criticizes the 2014 Sewol Ferry incident and consciously uses terms like "sink" and "crash". It also has an antifascism message and directly references Ray Bradbury's controversial book Fahrenheit 451.

Dracula - It's the story of the wolf waiting for Red Riding Hood disguised as her grandma except this time it's not a wolf, it's a dracula. He coaxes the little girl to trust him while warning her to beware of the dracula.

Milk - It compares the healing properties of milk on burns to ease the burn of heartache.

Boom Bang Boom - Describes a push and pull relationship by using a boxing match as a metaphor.

Spit It Out - A girl talks about a boy swallowing her heart and she's now asking him to spit it back out. Doesn't sound as bad but the lyrics are weird and without context it seems like the song is about a foodie.

Diamond - The girls compare themselves and their worth to diamonds.

When I'm Alone - Has some if the creepiest f(x) lyrics. Written by Carly Rae Jepsen the lyrics talk about making love to a ghost lover but in reality the song is about masturbation.
