Babelan
The only thing worse than a Lachlan is a Babelan, they did something nice, and now you have to pretend you like them.
You just got a free pizza from a Lachlan. Now you're a Babelan. Congrats.
Your Lachlan brother donated to charity. You're now a Babelan. Enjoy the guilt.
Your Lachlan friend helped you cheat. Now you're a Babelan. You're welcome.
