somebody who smokes a lot of “dill” if you know what i mean
“That guy’s such a dillhead.”
“Yea bro’s smoking dill.”
“Yes, with this bloodshot eyes, droopy eyelids, slowed mannerisms, accented food cravings, affinity for random laughter, and stench akin to that of a skunk, he’s definitely a dillhead who certainly, all day, smokes dill.”
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
