Fill 1/3 of the glass with 151. Pour the Kahlua over the back of the spoon slowly to keep the liqueur's separate. Then do the same with the tonic/soda water. Place the straw at the bottom of the glass and drink it all in one suck. The 151 and Kahlua will tear your stomach up, but the tonic water will settle it back down. This is why it is important to drink it all at once. They also taste pretty good mixed.
