metaphor
you say one thing is another. like if you said 'my style is gravity', that's a metaphor. your style = gravity.

simile
when you say something is 'like' something or 'as' ... as something. if you said 'got honeys like sand on the beach' that's a simile, (lots of) girls = (lots of) sand on the beach
