Does anyone else encounter stuff like this:
A couple of our groups younger members:
"Dude, thats AP14."
"Isn't"
"Look, it says here in the codex, its AP14"
"F*CK YOU, YOUR MUMS AP14!"
"Fair point, well made"
The funniest part, they are brothers, and their mum plays (the dreaded Hive Fleet Chlamydia) and biffed them both on the head after.
