When a girl loses a condom in her vagina after sex and doesn't find it until a week later and it starts to smell like seafood.
"Susan, I'm so embarrassed, I've been showering, but couldn't get the smell out. I found out i was a total megan fish. I'm so relieved!"

Get the Meganmug. This girl is like any sluy you have seen in any high school movie, she is a hoe. She loved black dick but will take mexican sometimes, she claims she changes but still acts like a hoe in socail media she is a little bitch that cannot fight. Ask any guy at your school about her and they will say "oh yea shes been fucked"

Get the Meganmug. Don't we all wish our name was Megan? This girl will be the winner of love Island with her amazing looks, brain and charm. If shes the one who is sporty and chills at the same time,Meet her at the netball courts but only if you're tanned with a six pack and good at lip synching with a good voice. If you're re the Molly May to my Tommy Fury, DM me, Brandon Nevarez.

Red headed biatch who has major daddy issues so she hates men. Typically obsessed with creepy ass shit like horror films or paranormal stuff. Definitely emo or gothic.
