I came up with this little idea when I was under pressure to get my friend a gift for his 18th.
I made up 'THE LITTLE BOOK OF SEXUAL INNUENDO COCKTAILS'
Basically all you have to do is search for cocktail recipies on the internet that have the dirtiest names. I even substituted our names into a few like 'the Konrad cum shot' and 'George's penisbutter cup'.
I wrote out the recipies on note paper then scanned and editted them on photoshop with cut out hentai pictures etc. that I thought went well with each recipie. I then went and got the pages printed for a mere $3 or something and holepunched the corner, stuck in a split pin and VOILA!
Its fun, personal and easy and I arranged it wrapped up with a nice cocktail glass ($10), umbrella(50c) and a swizzle stick(50c) in the shape of a naked woman. I think this is a great idea for anyone you think is willing to give cocktails ago, especially great for 18th gifts. And it only cost me $14
(Matt said it was THE BEST present he got this year!)
