press f4
A statement notifying people in certain multiplayer PC games (Most notably in Team Fortress 2's Mann V. Machine game mode) to ready up for purposes of a match starting. So named because the Function-4 (F4) key starts (or reduces time of) a countdown timer for an MvM wave. Usually used for the following reasons... 1. A teammate notices a sufficiently prepared teammate who has yet to press f4 and notifies them as such. 2. An impatient scrubby try-hard 20-something who can't wait 2 1/2 minutes for a wave to start shouts it into the microphone. 3. A N00B 10-14 year-old who thinks s/he's helping when almost everyone knows about it. (often shouting into the mic in a nasally pre-teen voice. Inversions usually occur in the following situations... 1. An engineer tells his/her team to stop the countdown so s/he can prepare sufficiently. (A competent MvM engineer can get all 4 (or 5) of his buildings ready in about 30 seconds. (usually about 50 remain after 5/6 readies)) 2. A teammate needs time to figure out upgrades. (Upgrade priorities are often common sense (metal and building health upgrades for engie, UberCharge upgrades for medic, resistances and speed for scout, afterburn effectiveness for pyro, etc. with slight variance for map and loadout.)
The Urban Dictionary Tee
The T-shirt was a birthday gift for my girlfriend and she absolutely loved it.

Happy that this tee is comfy and fits well. I wish the sentence was on the back too.
My wife absolutely loves her new T-shirt.
This looks like a weird design but it looks cool
This T shirt is the best piece of material to have ever graced this Earth. The fine quality fabrics and in depth definition, which is professionally implanted on the back of the shirt, which makes for some very interesting talking points. Thank you Pablo Parmesan.
Absolutely wonderful product! I bought this shirt for my son and he gagged with joy! Mariah Careystmas everyone!
I love it I bought me and my family some
Glad I had utmost FREEDOM OF SPEECH to express in articulate detail what evv it is the fk i was on a rant about that day. I haven't even received my shirt. I just a few moments ago placed the order. That is how pleased 😄 I am. Fk yeah fk yeah. Very empowering experience. My thoughts turned into type, that made some shi# happen. Having freedom of expression was most definitely...one fk ton of fun. A fk ton can be quantified as exuberance an joy beyond expectation. Fk yeah fk yeah. Awesome>>>
Proofread much? She might seem "quite"? Please fix the spelling to "quiet". Can't believe I was considering this purchase...
Damonism T-shirt :+) I found this by accident while surfing through your site. I love this shirt. I bought one and wear it when I feel frisky.
Another hit!
Great shirt, great service. A big thumbs up👍🏻
I always get so many compliments when I wear this (my favorite) shirt. I have been able to give out my phone number to lots of nice old men and my parents think it's great that I have so many nice mentors grooming me into a nice young boy who is willing to "follow the rules ".
Very comfortable and love the tyoeface
