look up any word, like columbusing:
 
1.
Stereotypical jock or football player type. Into all things sports, and not much else. Attracted to skinny, fake tanned (to the point of being orange) blondes with a greater focus on breast size than personality. Bluesharks often feel threatened by people smarter than themselves, especially in groups conversing. If in such a situation, it is common for a Blueshark to yell something along the lines of "Yeah, Footie!", in a feeble attempt to join the conversation.
Person1: Great party, huh?
Person2: Meh, I wish they'd turn the music down and put the footy on.
Person1: Dude, you're such a Blueshark!

2.
The ramblings of a techno-phobic old lady who is unaware of the technology on her mobile phone. Good for about 7 days of laughing and also as a constant reminder that old people are not more intelligent.
Does this phone have blue shark on it?
WTF, do you mean blue tooth!!
