It is a made up word from the show iCarly. Wade Collins uses it to describe Freddy,
Carly, Sam and
Spencer. The writers of the show try to keep it a mystery but there is alot of speculation in the fanbase. The Merrian-Webster dictionary defines "hob" as a synonym for mischief or something illegal. Therefore, if it's gross AND illegal it most likely is one who is a necrophiliac or one who indulges in
incest. However, judging by iCarly's target demographic of 10-
15 year olds, it probably means
incest since negrophilia is usually related to gross-er matters. Many fans believe that it may mean a prostitute; however, they forget that they replace "whore" with "skunkbag" just the way they replace "dipshit" with "dipwad."
