flens

From Swedish, meaning dick-ckeese. You know, that yellow stuff on your cock.

Man, there's a lot of flens on my dick. I knew I should've cleaned my penis at least once a year.

Flen’s Dick

Its huge, Massive.
Everyone hates when flen jokes about his dick (Nut nc they’re jealous of how big his cock is)

Flen’s dick is massive, Not even King Kong could handle it
Flen stop joking about your dick. Gross.
