1. A person that is a huge douche bag and constantly kisses ass to get where they are. They tend to be dull boring assholes with no sense of humour or heart. They are also usually pussies and are never willing to bend the rules to help a comrad out. Ball lickers tend to get a lot of managerial positions in life which can really piss off a genuine guy that is subject to working for him. At every school i've been to or for any organization I have ever worked at, there has always been a madd ball licker that likes to ruin my fun.
2. A flaming fruit loop that likes to pleasure his boyfriend by licking his gonads. This type of ball licker is gross but to be fair, they can still be good citizens or nice people.
3. A girl that is sexually bold. If your wife licks your balls, power to you. However if you just met the girl and she wants to lick your balls she is downright scandalous and you should get tested as soon as humanly possible.
4. A guy with nothing to do that spontaniously picks up a billiards ball and licks it for no particular reason. Allthough it is odd, I can't think of anything wrong with that type of behavior. Mind you this type of ball licker is extremely rare. Infact I have yet to come across one in my travels.
ball licking manager: Hey Miller, you're fired.
Ranting Miller: Good I don't want to work for you anyways. Trust me guys this guy is a huge ball licker. How do you think he got his job anyways. Obviously from licking so many balls.
ball licking manager: You're choice of words are most foul and inappropriate to be used inside a steel mill. I request at once that you use restraint and be more professional. What will the CEO think if he see's my men out of line.
