Take this for example:
In this video, at 1:04 to 1:10, the person goes on rapping with a rhyming word at the end of each line, but he pauses before the end of the last word and, being humans, we predict the next word (due to the hint from the rhyme) that he is going to say but he avoids it intentionally. Is there a word or phrase for this word play?
...and the beat still knocks when I sort my socks
I'm five foot eleven of sex
from the tip of my head to my gorgeous...
Not the best example I could find but I think it sums up my point quite well.
