M67
A little grenade that explodes like a fart in a tight pants. It might not look scary, but it will rip your face off and make your mom cry.
My buddy got blown up by an M67 and now he smells like burnt pizza.
That grenade went off and my ears are still ringing like a bad DJ set.
I threw an M67 at my teacher and now she's screaming like a toddler who lost her juice box.
