Fucknod
Abbreviated form of the term Fuck Nodule. A total fuck. Someone who is such a giant fuck that it is instantly and painfully obvious that they are such. Even in a group of fucks the fucknod stands out as a particularly worthless and irritating fucker.
The entire cast of Mad TV is a bunch of fucks, but Michael McDonald, the douche nozzle who plays that fag weasel Stuart, is a total fucknod. God I hate that bastard.
