rub it on your chest

if u wanna buy, sell, r trade with someone n they refuse the deal in other words don't wanna let go of what they r holding you tell them to rub it on their chest basically saying to just keep it in their possession n caressing it on their chest talking bout "ill never let u go" in other words "rub it all over ur chest you can keep it"
