You know you've played too much TF2 when...

[Hawkers]

you start screaming Heavy quotes at school!

How do you know when you've played too much TF2?

[solofowaffles]

You taunt everyone you see.

You immediately think of Pyros when watching the first bit of Star Wars Episode 4. :p

Oli gets backstabbed by me.

[Thermal755]

When someone(me) starts calling out "Incoming" in a Heavy voice when I see a teacher.
When you start poking people in the back with a pen,and taunting them for a backstab.
When you annoy people with the scout voice,repeating "Need a dispenser here."
When playing a sport in Gym,you scream out "Run Cowards!!!"

[[DR]S|Pvt. Voop_Bacon]

When your irl battlecry is the pyro's (when he's taunting)
