Lad bands
A band of lads who make music that's loud, messy, and usually has something to do with getting laid. They're like boy bands, but they don't suck at being lads.
My brother's in a lad band. They wrote a song about stealing the teacher's coffee and eating the principal's lunch.
The lad band at my school sings about how they're going to fail every test and then get drunk.
My friend's lad band just started a trend of singing in the shower during lunch.
