The most annoying negitive come-back one can say to anything someone else might say, mostly used for complaints, but can also be used as a form of jelousy. Meaning either there's nothing you can do, you dont want to (like "have fun, it's going to suck, I'm not going."), you're jelous, and/or you dont really give a shit. Taken from the statement "That sucks," but shortened to "sucks."
Make sure to say it in a "I don't give a shit" tone, and repeat often to annoy.
Your Friend: "Dude, my parents are trying to send me boot camp!"
You: "Sucks."
-Later-
Your Friend: "Hey I just got tickets to Hemp Fest"
You: "Sucks."
