It's a lyric- The song's called Holy Lance Explosion Boy, the one I said was about him f**king like five girls and getting them all knocked up because they didn't say to wear a condom
Bro, this whole 'Len Kagamine' thing aint gonna work out too well when I try to impress someone with this playlist; 'What's this song about?"
"He knocks up like five women in a row"
"What this song about?"
"Puberty hits and he wants to f**k every girl he sees"
"What this song about?"
"...It's called Merry Sex-mas..."
