Working Man Pants Is All I Wear

Gallivant means nothing to me
Britches is a word I've never seen
Rigmarole I think I heard in a dream
Hoodwink from red riding hood quite possibly
 
I go digging through my skull, skullduggery?
Jalopy, my favorite car, same as Archie
Brouhaha is perhaps when a friend laughs
as shenanigans land in a crash at bottoms of silly summits  
and later leave bros flummoxed
whatsit all that's left to say, besides  
the phrase, I'm not that fancy
