main battery

A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a gun or group of guns, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles.

Main Line School of Rock

If you go here, you’re either gay or depressed. Most likely both.

Everyone is addicted to vaping.

The teachers and directors are great, the kids are questionable at best.

Let’s be real, the music is mediocre. Every now and again you get an absolute banger but cmon, don’t kid yourself. There’s always at least one song that’s inconspicuously placed in the middle of set one, hidden amongst the decent ones. You know which one.

But if nothing else, main line is better than downingtown. It’s honestly shocking they did bass gods before us.
