From "Sea Songs & Shanties" by Capt. Whall, p.69. This (Blow The Man Down) comes from the old Alantic sailing packet ships. "Blow" in those days was equivalent to "knock". The 3rd mate in tose ships was endearingly termed the third "blower and striker", the second mate being the "greaser".

"They gave me three months in Walton Jail
Way-ay, blow the man down
For booting and kicking and blowing him down
Give me some time to blow the man down"
