m4
The reason every teenage boy thinks he knows everything about guns and how to shoot them properly.
"My brother thinks he’s a Navy SEAL because he saw an M4 in a movie. He can’t even shoot a real gun.", @BrotherHater
"I asked my dad what an M4 was. He said, 'It’s a gun.' I said, 'I know that.'", @DumbKid123
"My friend tried to explain the M4 to me. I fell asleep.", @SleepyStudent
