The Bristolian then lay in wait in the bathroom, along with John James and JJ. Sam went in to brush his teeth not long after, and the trio found it hard to suppress their laughter as they too set about cleaning their teeth.
Once he had finished, Sam gave his toothbrush a disdainful look before vacating the bathroom, leaving Josie, John James and JJ in hysterics in his wake.
After a few minutes the graffiti artist returned to the bathroom and demanded: "Was that a funky tasting toothpaste or did you just terrorise my toothbrush?"
He continued: "I thought, 'I've never felt this minging after brushing my teeth'," and admitted that it had tasted like orange juice 20 days past its sell by date. "The aftertaste gets worse and worse," he complained. "It wasn't that bad while I was brushing my teeth."
"It's foul," agreed David, who had headed in to find out what was going on. "Rather you than me!"
The group then left the bathroom and Sam warned: "That wasn't on, Josie." The 25-year-old claimed it had been in retaliation for an earlier incident. "It all started when you put your dirty ballbag in my mouth," she told him.
