49er 

Male gold digger.

"Who's this wigger Kevin Federline?"
"Some corny ass 49er who was stupid enough to knock up Britney after she blew all her money and went crazy."
"And who's this scrub on the bench Kris Humphries?"
"You bite your tongue. You're talkin about the most soulless, ruthless 49er there ever was."
*sheds tear*

49er 

A gold digging woman that is rated 4/10 but thinks she is a 9/10.

What's up with these 49ers thinking they deserve $200 first dates?

49er effect 

A San Francisco-Bay Area term referring to members of the female gender living in an inflated state of mind leading them to believe they are way hotter than are in reality. More simply put, a girl who is a 4 and acts like a bitchy 9.

Dude, I am so frustrated, I need to get out of the San Francisco swamp, all the girls here are under the 49er effect.

A guy that loves having male on male intercourse, and only wears team colors when his team is winning.

Guy 1: You see those guys giving each other head in the alley.

Guy 2: Yeah they must be 49er fans, but there not wearing there colors because the 49ers lost last night 1,000,000 to 0.

49er's fan 

Fans of the San Francisco NFL team who all seem to live in the past and compare opposing teams of the present with their teams former greatness and obnoxiously hide behind 5 Superbowl wins their current team had absofuckinglutely nothing to do with.

49er's fan: The Seacocks suck. They have no D.

Hawk's fan: Look who's talkin trash! What's your team done lately? Win a couple games, did they??? Good for them.

49er's fan: We won 5 Suberbowls. Your team choked in Superbowl XL.

Hawk's fan: I said lately, fucktard. Nevermind, I forgot I was talking to a 49er's fan.... GAWD, I need a latte.
