Some of the penguin's finest insults (Some are by me, some are by others):

Disclaimer: We all make mistakes and I typically don't give people that kind of treatment, but sometimes, when someone is really thick, arrogant or just plain stupid, the aid of the verbal sledgehammer is neccessary.

"Yeah, you do that. And once you fucked it up, you'll go get me a coffee while I fix your shit again."

"Don't add me on Facebook or anything... Because if any of your shitty code is leaked, ever, I want to be able to plausibly deny knowing you instead of doing Seppuku."

"Yep, and that's the point where some dumbass script kiddie will come, see your fuckup and turn your nice little shop into a less nice but probably rather popular porn/phishing/malware source. I'll keep some of it for you if it's good."

"I really love working with professionals. But what the fuck are YOU doing here?"

"I have NO idea what your code intended to do - but that's the first time I saw RCE and SQLi in the same piece of SHIT! Thanks for saving me the hassle."

"If you think XSS is a feature, maybe you should be cleaning our shitter instead of writing our code?"

"Dude, do I look like I have blue hair, overweight and a tumblr account? If you want someone who'd rather lie to your face than insult you, go see HR or the catholics or something."

"The only reason for me NOT to support you getting fired would be if I was getting paid per bug found!"

"Go fdisk yourself!"

"You know, I doubt the one braincell you have can ping localhost and get a response." (That one's inspired by the BOFH).

"I say we move you to the blockchain. I'd volunteer to do the cutting." (A marketing dweeb suggested to move all our (confidential) customer data to the "blockchain").

"Look, I don't say you suck as a developer, but if you were this competent as a gardener, I'd be the first one to give you a hedgetrimmer and some space and just let evolution do its thing."

"Yeah, go fetch me a unicorn while you're chasing pink elephants."

"Can you please get as high as you were when this time estimate come up? I'd love to see you overdose."

"Fuck you all, I'm a creationist from now on. This guy's so dumb, there's literally no explanation how he could evolve. Sorry Darwin."

"You know, just ignore the bloodstain that I'll put on the wall by banging my head against it once you're gone."
