It's not the length of the poem that matters, rather it is the thought that goes into it. A short poem to your Valentine can easily be more powerful than a long one. It is the content that matters. In fact, if you're taking the time to write something of your own, you're probably on the right track. Don't go for the "roses are red, violets are blue" variety of poems. Don't give her a card with a prewritten poem in it.
Who doesn't like being romanced every now and again? It's the little things that count, and what better way to show a little love than by sending short love poems to that special person in your life? Flirty poems are an especially great way to show your romantic side if you're dating, say, an English major. But honestly, the love poems below will take you far with anyone who enjoys the art of words and the lovely ways they can be woven together.
When people think of poetry, most often they think of a romantic, meaningful genre of writing within which people can express their deep wells of love, admiration, and longing. This is not that poetry. The creepy poetry on this list proves that poetry doesn't have to be cute and that, like any creative form, it can be used in any number of ways. In this case, poetry is used to create dark, unnerving stories and scenarios, none of which are even remotely pleasant.
Roses are red, chocolates are brown, I expected nothing, but you still let me down. Roses are red, pizza is too, I ordered a large, but none is for you. Roses are red, ignorance is bliss, rhyming is hard, show me your tits.
