Let's analyse the lyrics to T-Pain's hit single "Buy U A Drank"

Baby girl whats your name? [IOI too soon / interview question]
lemme talk to ya, lemme buy you a drink [asking permission, buying her time]
im t-pain you know me convict music NAPPY BOY ohh wee [let her ask YOU]
i know the club close at 3
whats the chances of you roll'n wit me [Don't ask the chances, tell her to come]
back to the crib show you how i live
lets get drunk 'n forget what we did [Surely she'd want to remember if you're gonna have such a great time?]

(chorus)
i'ma buy you a drink oh thennnnnn
i'ma take you home with me
i got money in the bank [Show, don't tell]
shawty what you think 'bout that [Why do you need validation so bad?]
ill be in the grey cadillac [Lame choice / colour of car ]

As a side note, I'm a huge fan of this cover

You forget the rarely discussed PUA "Autotune clause"

Autotune clause - anything said with an autotuner being used (to make it sound much cooler) has the reverse psychological effect that the statement would have if an autotuner was not present.
