The laziest and slimiest friend anyone can have.. Most likely to play zombie games around 2 in the morning whilst complaining about download times on actual games that may prove to be worth playing. Has a bad habit of finding tarnished napkins laying around and picking them up, then proceeds to have an internal tweakathon and won't shut up about it for months. This can also be short for "Nibert Slugerton" the grimiest of the gross.. It is quite possible when you're kickin' it with the doods having a grand ol' time he dips out on you for hours, sometimes days and won't mention the incident and play it off as if he was eating doritos watching the simpsons.
Jeeb: Man that Nibert Slugerton is such a pile of junk, he didn't even give me back my bang sack...
Tyler: It actually wasn't NIBSLUG this time, TWAS I who stole the bang sack..
