Uk slang, common in private schools.

Bunder is a portmanteau of the words banter and chunder, and used to mean vomit/to vomit.

Usually refers to vomiting after a fun night of heavy drinking and partying (hence the inclusion of the word 'banter').
"I was so trashed after last night that I bundered in the taxi on the way home!"
