Alphabet Train is one of the recurring improv games that was introduced in Season 18 of the improv comedy show, Wild 'N Out, on VH1.
Description[]
The team members will make a circle. Then the audience says, "F it up (6x), on the alphabet train...". A letter will pop up and the person in the middle needs make a rhyme related to the topic. If someone messes up or can't think of a rhyme, they get a buzzer, get kicked out, and the audience says, "He/She F'ed it up (6x)".
