Bitch-effort

When a guy changes who they are in order to impress or get a girl to like him.

Dave had never shaved his legs in his life, until the day Mary said she likes smooth legs. He's such a bitch-effort!

last bitch effort

noun, potentially a verb last bich ef-fert: That person I met online, hung out with a few times and drops off the face of the Earth. All of a sudden they resurface after a few weeks with an "explanation". Usually with the "I wasn't ready" excuse.

Me:"You know that guy I slept with a few weeks ago and really liked but he decided to hit it and quit it".
Friend: " Yeah"
Me: "Well I finally heard from him yesterday-he said 'I am not really good at this and just not ready for it. It's not fair and I'm sorry'."
Friend: "What the hell does that mean? Why did he even contact you again after you stopped talking to him"
Me: "Not sure, but it was probably just a 'last bitch effort' because there were no other takers either".
