A completely useless creature that does nothing but cause nuisance and aggravation.
Originally coined in the US Navy by sailors tasked with washing decks clean of the massive amount of avian excrement created by sea birds that shit all over everything.
Has come to define any living creature, human or otherwise, that is without redeeming qualities.
Sailor: "I just got assigned to swab the fucking launchdeck... The goddamn shitbirds flew over last night and completely destroyed it."
The act of bidding something you're not going to pay for, typically used on eBay and other online auctions. Shitbids are often a ridiculously high price much, much higher than the value of the actual item being sold. A shitbidder usually targets the person selling the item, often with the intention of making the seller lose money due to a personal grudge.
I posted something on eBay and somebody shitbidded it up to $5000. Now I have to pay to relist it again because he didn't pay.
A portmanteau of the English swear “shit” and “Squidward”, the name of a character on SpongeBob SquarePants. Typically interjected in situations of surprise or shock, however can also be used as an insult.
