what does that mean?

innuendo about his manhood.

Alius - if you read all the lyrics, you can see that he is bragging about all his possessions. So he has a huge house, with a sit down elevator, on 12 acres.

You can't take just one line out of a poem or song and expect to make sense out of it. Look at all the other lines, too, for clues.

Yeah Sully is correct he is bragging about his estate.

yeah . you are right but now i think u read the text so can you tell
what is "I got a Maybach, with the partition
And they call it Flat head baby, flat baby the new edition
It’s Timbaland man beats , that make you bump that" mean ?
in the same lyric
