What is the difference between homonyms and rhyming?

Oh, dude, homonyms are like those Words that sound the same but have different meanings, you know, like "bark" (dog noise) and "bark" (tree skin). Rhyming is when Words have similar sounds at the end, like "cat" and "hat." So, like, homonyms are all about meanings, and rhyming is just about sounding cool.
