The Ramones wrote this as a salute to their fans - it's about having a good time at a show.
Some fans interpret the song differently, however, as "Blitzkrieg" is a German term meaning "Lighting War." The Blitzkrieg was Hitler's army and in this interpretation, the Bop in the song is the march that the soldiers do. Here's a look at this interpretation:
"Hey ho, let's go" - The soldiers marching.
"They're forming in a straight line" - The soldiers are standing in a line.
"They're going through a tight wind" - Cars going down the autobahn.
"The kids are losing their minds" - Boys being turned into soldiers by Hitler.
"The Blitzkrieg Bop" - The soldiers march.
"They're piling in the back seat" - People piling into vehicles to get on the autobahn and soldiers piling into vehicles.
"They're generating steam heat" - The engines were so hot they started to steam.
"Pulsating to the back beat" - Germans getting pumped for war.
"Shoot'em in the back now" - Hitler being shot.
"What they want, I don't know" - Why Hitler was in the war.
"They're all revved up and ready to go" - The soldiers getting ready to fight.
