"Da Butt" = total classic. In 20 years, people will still be doing it.
Considering that reading just even reading the words "Da Butt" is making me do a somewhat goofy voice saying "Sexay, sexay!", I feel good about the song's prospects.
And when is the last time you heard somebody say "<someone> got a big old butt" and NOT wanted to say "Oh yeah!" These are the things that make a song a classic.
In my head.
Which is firmly planted IN DC and thinks Junk Yard Band's "Beef Jerky Time" is also a classic.
Oh, wow, Junk Yard Band! I am not and have never been a DC person, but once when a friend and I were walking around Boston at night inhaling non-legal substances, he carved "John Wayne" into a telephone pole because of that band.
I think "Loose Booty" is my favorite tune of theirs.
