The guy she’s seeing is a chump (though “chumpy” is also an all-purpose noun in the same sense as “motherfucker”/“-ing”)

Humpty Dumpty (“had a great fall”), or the Humpty Dance… note that she says “dump me” in next verse to play on the name

To keep one’s composure (Missy’s reading thereof seems a direct antecedent to the flat recitation of “hips and thighs/oh my/stay focused” on Jim Jones' “We Fly High,” though it may just be coincidence)

Missy is really good at making assonance where it has no right to exist, and we are all the better for it (more urgently, she is asking you to picture her rollin' here)

Weed (“sticky icky”)

“I Can’t Stand the Rain” by Ann Peebles

This inhalation of marijuana smoke does not appear on the radio edit, though the track retains a hazy and surreal aura without it

She’s recalling a hook from the song, “Can We” by SWV; she and Timbaland were both on that track.

She references Cheryl “Coco” Clemes, the lead singer of SWV, in the next line.

Missy and Tim are from the Hampton Roads area of southeastern Virginia, which is very near Virginia Beach
