Tequila brand Jose Cuervo has created a brilliant application for party animals. It is called Howl and has a very appealing functionality.
You create a group of your friends and when you come across a great venue or bar and want to hang out, you just send all of them a special "howl" message with details and location. Recipients can then reply as to whether they like the idea and will participate in the spontaneous event.
This makes life easier and eliminates numerous calls and SMS messages to gather friends together. It saves valuable time to party ; )
Jose Cuervo also created a series of funny Party Animal videos with natural scripts and real friends acting as voiceover artists. The videos show how guys interact between each other, showing all the mischievousness, all the humor and all the embarrassment.
