Ping pong puppy

The type of unattractive girl that will drop her knickers at the first sign of male attention and then will run round after them like an excited puppy. Only to run after another guy as soon as they think they can get an advantage from it. Only to go back to the original guy if the second one doesn’t pan out for them.

The cycle then repeats ad infinitam.

“I see Shelley isn’t sniffing around the new manager anymore”
“No, she still think’s Kieran is gonna leave his wife”
“She’s such a ping pong puppy”
