An early, dedicated follower of Aerosmith. Aerosmith remarked at a concert that their audience members wore overwhelming amounts of denim, and said they looked like a Blue Army.
You fight in the Blue Army? Hell yeah, I love Aerosmith.

The more badass half of Red vs Blue. Theyre the ones who wear the blue armor!
Damn those Blue Army guys just beat our ass again, Private Donut!

A large group of boys. They are constantly getting "blue-ticked" by girls.

This means that they are being ignored by all of the girls that they speak to on WhatsApp.
Look at that Blue Tick Army outside, it is quite embarrassing.
