Hand them out to people in the group and do an in-house rally shaking and saying the slogan. Find ways to imrovise musical tones, like the higher sounds 1st, then the lowest . Take them into an otherwise boring meeting, parade on the street. They are fun to use in a variety of settings.

Start with one
ask them to shake it while ALL say
“Hey, hey, hoe, hoe racism has to go”
Have the next shake theirs and ALL say
“Hoe, Hoe, hey, hey love and kindness is here to stay

Have the next initiate slogan alternating
hey, hey, hoe, hoe, __ ___ __ has to go
Hoe, hoe, hey hey ____ ____ ____ is here to stay

You can organize the sounds in various creative ways:
lower tones doing the hey, hey, hoe, hoes and the higher ones doing the hoe, hoe, hey, heys for example.
