Anybody know why Bam Margera named his film "Haggard"?

its probably the name of a band or something but i was just wondering?

welllll no answers but i found out from cha cha anyways.. bams grandpa
named him haggard because when he was little he kept running his head
into things... haha.......if anyone wanted to know
yea cha cha is stupid........ i should have looked up the word..
lol........because cha cha told me how bam got the name BAM rather
than why he named the movie haggard. thanks to you who gave me the
definition! haha
