Blow off is a British slang term usually used by children to mean "fart". This term was prevalent up until recently but its use seems to be declining and the bawdy American version which means to ignore, or snub, is taking over.
This is one of the reasons Americans are laughed at in Britain as it causes some humour in British households.
