a commonly used prank usually when someone is sleeping or heavily intoxicated. Multiple people are required.
Before it is explained, i will state that the person sleeping is person 1, the speaker is person 2 and the butt person is person 3. The intoxicated/sleeping person (person 1) will be seated or preferably laying down on a couch or bed. one person(person 2) will lean towards the intoxicated person and began saying, "chugachugachugachugachugachugachugachuga," similar to the noise made by a passing train. This gradually gets louder. As the volume increases, another person (person 3) pulls down their pants, shorts, or whatever covers their round bottom, and places it at a 90 degree angle with person 1's face. Now it all comes to turn. person 2 (the speaker) will yell, "WATCH OUT FOR THE TRAIN"!!! in person 1's ear. person 1 will wake up, shocked at the noise he just heard. He will shoot up from his laying position, directly into person 3's prepared butthole, who will then release a fart/poopy from his rectum, completing the prank. This prank most likely will result in death or severe injury due to the raging anger of the recipient.
