Need to find name of song?

it was a r&b song i think last year maybe. i remebr hte video it started with a black guy seeing a pretty black girl. so he starts follwing her down the street and hes trying to convince her to listen to him. and then they end up at his party later night. lyrics had like "beg your pardon" i think? he was also a short stocky guy i think. with shades
