What is it that tastes like gravy

What is it tastes like gravy : boys I bet you don't know
Can you guess what tastes like gravy : it's tight if you really want to know

I taste it last night : the night before
If I keep this appetite : I'm going to taste it a little more

Now the gal that let me taste it : they put her in jail
But she didn't need nothing : to go her bail

Now if you don't know : I tell you who do
Just see Tampa Red : and his best gal too
