Term coined by KSI in the sidemen eating one colour food for 24 hours challenge. It is the blug of the pig that has a distinct taste of grapefruit despite being an internal bodily fluid of a pig. Nobody knows what it is made out of but Jj and it should not be confused with "pig blood".
Josh: *has a pink glass of drink*
Vikk: I reckon it's grapefruit JJ: I think it's uh pig blug
It is something so weird, confusing, bad, pathetic that goes straight past the point of being ironically funny and just leaves you feeling empty like you want to laugh but there just isn't enough to laugh at. Quite often describes Indian social media posts.
Derived from a cryptic petroglyph found in the Lucero Wash outside of Las Cruces, NM, blug has evolved into a broad term generally referring to a large, unkempt, rude, sweaty, mouth breathing, "ghetto" person, or perhaps vehicle belonging to said person. Subsequently, the word has been "acronymized" to mean Big Lazy Ugly Guy (or Girl).
"Did you see that blug walking into Wingstop?"
"That minivan with the neon undercarriage lights and the Raiders sticker is pretty blug."
Upon witnessing a 300 lb. woman climb out of a car in the Walmart parking lot, Michael points and exclaims, "Blug!"
