if it has meter it could just be iambic, it could be something else.
it doesn't need to be pentameter, it could be a mixture of meter by way of different forms; ballad, limerick, haiku, sonnet, free verse [which doesn't have a regular meter] and blank verse which is generally iambic pentemeter...there's a lot more [check out here]
