I love this patch! It's not vague or leave any room for doubt. The Do Not Piss Me Off Patch makes it clear that you just need to back off. It's one of the 2nd Amendment Patches because it's also very pro-gun ownership, which is what the second amendment to the constitution guarantees.
The second amendment quite clearly says that all people have the right to keep and bear arms. It is one of the ten original amendments to the constitution that make up the Bill of Rights. This amendment has been challenged by those who aren't sure owning guns is really the best way of keeping the peace. Those on the other side make the point that bad guys, thieves, and murderers are going to find some way of getting a gun, so we all must have the right to protect ourselves.
While this patch doesn't make an overt second amendment statement (it's not saying 'We want our guns!'), it does show a hand with a gun clutched in it, ready to fire at anyone attacking him. This is such a great patch to wear around those who tend say stupid things that make you want to smack them. Let them know it's better if they don't piss you off. And if they do, well, you gave them warning!
This patch is round and measure three inches across. It can be ironed on to most materials using the heat activated glue on the back. If you want to use it on leather, sew it on. It makes a nice decoration to any piece of clothing, or you can use it to cover any rips or tears in old clothing.
