A fun, loveing, athletic chick. Usually has a great sense of humor and can make anyone laugh. Usually a very strongly opinionated person. Usually very popular and has lots of friends and lots of admirers. Normally, extremely beautiful and striking to the opposite sex with great facial and body features. Usually very intelligent but at times can be slow, or have trouble understanding things. A very memorable person. Very sweet, but very strong phisically and mentally so don't get on her bad side. Definitely a person you want in your life, and the kinda person you want to be liked by.

The perfect dream girl. The kind of girl that's on your mind all night. The kind of girl worth losing sleep over. Has a smile that you would do anything to see.
That girl is a total Guinevere.

A girl who, while she is a lovely person, is constantly cockblocking people, typically without realizing it. (Can simply be referred to as "Gwen." Male cockblockers are referred to as "Agravaine" or "Uther.")
Merlin Fan #1: I swear Merlin and Arthur were about to kiss in that last scene, but then Gwen walked in and ruined the moment.
Merlin Fan #2: Dammit Guinevere, you're such a cockblocker!
