Words You Can't Recall

Once you make a vow,
as a token of promise
from it you kowtow.

Once you make a fib,
as a token of fiction
from it you ad-lib.

Once you make a claim,
as a token of demand
from it you enframe.

Once you make a slip,
as a token of blunder
from it you flop-flip.

Once you make a slur,
as a token of insult
from it you demur.

Once you make a call,
as a token of your word
from it you free-fall.
