“We want a pitcher, not a belly-itcher” is a child’s rhyming baseball chant. “We want a pitcher, not a belly-itcher!” has been cited in print since at least 1971.
 
“We want a catcher, not a belly scratcher” is often added to the chant and has been cited since at least the 1990s.
 
“Two, four, six, eight, pitcher’s got a bellyache” is an older baseball chant.

Here is also how we played: with whoops and jeers (Hey batter batter swiiiiing), absurd derogatory rhymes (we want a pitcher not a belly itcher), with the absolute, tireless enthrallment of children who have latched onto a working solution.

Ayup… which is why baseball is such a hetero sport. They’re always screaming “We need a pitcher not a belly itcher” while if it were a gay sport they’d need catcher’s too… oh wait, they yell “We need a catcher not a booty scratcher!” too don’t they? Dammit! I thought there was a funny joke in there somewhere.

Gender differences show up in playground rhymes. Boys prefer gross-outs, ‘gotcha’ and ball field banter – “We want a pitcher, not a belly-itcher! We want a catcher, not a belly-scratcher!” ….. Girls go for more complicated cheers, hand slapping chants, dances and jump rope rhymes. (Helms, 1995, p.2)

belly itcher
In baseball, a lousy pitcher. Comes from “We need a pitcher, not a belly itcher!”
The Detroit Tigers are a great offensive team, but they don’t stand much chance of post-season play. They have too many belly itchers.
