I have already written enough on how to get success with your best man speech. Now, let’s consider it from another perspective. Here’s a list of things you should consider doing in order to end up with an awful best man speech.
Procrastinate: Why hurry? You have enough time to prepare for your speech. In fact, the best time to get started is the night before the wedding day.
Do not do the research. Why should you? There are loads of ready speeches that are available online. Just pick anything that comes your way and go through it once or twice. Change the names, places and those stories and the speech is all yours.
There’s no need to write the best man speech. An impromptu speech is always a good idea. After all you have other stuffs to look after, don’t you? So, don’t bother to compose a speech. Just jot down a few points on a piece of paper and you will do fine.
Share funny and not so funny stories about the groom and his ex-girlfriends. This alone will liven up the reception instantly. So, don’t hesitate. By the way, if you know some secrets about the bride this is the time to reveal them.
It’s almost customary to drink a couple of bottles of wine as soon as the wedding reception begins. Don’t worry about your speech. Best man speeches only come after a couple of other wedding speeches. So, drink your ass out and have fun.
Let your best man speech be long. The longer the better. Just grab the microphone and speak your heart out. Just ignore if you see some of the guests leaving the reception area or begin speaking with others.
Finally, you are not required to rehearse or practice for your speech. As said earlier, simply memorize the speech and deliver it extempore. Come on, you can do it.
Well, I think that’s enough to sink your best man speech. Go for it. And if you succeed to mess up your speech do consider posting an account of it here in the comment section. 
However, if you have other ideas and want to succeed with your speech instead, there are enough information on best man speeches right here in this website.
