Ooooo that's fun, cool name considering a Barracuda is a predator of the sea, also it's very long and tube like ... Similar to a sub I guess.

But I believe this particular track is actually about a misogynistic, predator within the music industry at the time who they wanted to call out. It's a very very interesting track lyrically when you think of what a Barracuda is and if you apply that as a description to a person you can see that that person... Wasn't the greatest person to be around.
