"Bommy" or "Bommie" by defenition, means "
Bonfire" by all those Liverpudlian,
scouse mortals who use it once a year to describle
bonfire night!
"Are you goin down the wrecky, to watch the bommy?" or in real
english, "Are you going to the recreational
field to watch the
bonfire, as it appears to be bonfire night?"
