Contextual Analysis of "clickity" in Lyrics

go clickty-clack

i like boys dark like alder side

with a pitter pat

the car horn beeps

i don't remember getting on

clickity click

ridin' on a southbound train

only helps to fan the flames

you can hear my high heels walking on

i'm carrying my bag of bones

wah wah. he made the freight train boogie as he rolled down the line. i'm headed for the station with my pack on my back

i hear the whistle blowing

rackety

clack
