Travis Barker and Kourtney Kardashian flirt using Misfits lyrics: ‘I want your skull’

And here we had them pegged as Black Flag fans.

Travis Barker and Kourtney Kardashian’s mall-goth romance has progressed to the “creeping out the normies” phase, as the pair flirted on Instagram Monday by swapping lyrics from a Misfits song in the caption and comments of their post.

“I want your skull,” Barker, 45, captioned a video of himself holding up Kardashian, 42, who duly responded with the next line in the punk classic’s chorus, “I need your skull.”

Creepy as the lyrics may scan, the couple actually went with the most innocent option from the song available: Other lines include “Corpses all hanging headless and limp, bodies with no surprises” and “Demon I am and face I peel.”

The visual part of the presentation sadly hewed a bit more rote at this point: You’ve no doubt seen Kravis making out in this pose multiple times at this point, perhaps most recently while surrounded by costumed employees at Knott’s Scary Farm last month.

The couple began dating in January and each has children of their own — possibly why they didn’t reference another Misfits classic, “Last Caress” to reference, itself built around the lines, “I’ve got something to say, I killed your baby today.”

Kardashian is mom to Mason, 11, Penelope, 9, and Reign, 6, whom she shares with ex Scott Disick. Meanwhile, Barker has teens Landon, 18, and Alabama, 15, with ex-wife Shanna Moakler.

Barker’s been keen to highlight his punk credentials throughout his relationship with Kardashian: He wore a Subhumans shirt — a band that released a song called “Mickey Mouse Is Dead” in 1983 — for a blended-family May outing to Disneyland.
