A person who lives in the lab, runs experiments like a maniac, and forgets to eat or sleep because they’re too obsessed with their work. They’d rather die than leave the lab.
My lab rat friend missed their mom’s birthday because they were testing a new chemical.
She texted me, 'I forgot to breathe today, I was too busy proving my theory.'
He’s been in the lab for three days straight. I think he’s gonna turn into a rat.
