The term 'obnoxious sort' can be broken down into five words, each of which is a three to five letter acronym. The first is ASS, which stands for 'arrogant, selfish, and stupid'. The second is BOZO, which stands for 'boorish, obnoxious, and zany'. The third is CREEP, which stands for 'creepy, repulsive, and evil'. The fourth is FINK, which stands for 'foul, insufferable, and nasty'. Finally, the fifth is SNOT, which stands for 'sneaky, nasty, and odious'. All of these words describe someone who is unpleasant, rude, and generally disliked by others.
