She about this lumberjack so she gonna get this log cause
I'mma get that thundercat when I get up under that thang
Play on words with Log and Thundercat.
Big Boi, in this case, is a lumberjack and the girl wants the log A.K.A. his penis!
While she get’s his log, he gonna get that Thundecat, also known as her vagina.
