In Upper Guinea Crioulo it is «(put your enemies) under your feet so you can rest your feet on them.” (Source: David Frank in this blog post )

In Whitesands is is «door-cloth.» «This would be that rag at the door that you use to wipe your feet after walking in the dirt or mud. Similar to a doormat. The point of comparison would be that a door rag is so low in value/position compared to the one using it.» (Source: Greg Carlson)

Non-metaphorical ways to translate this include:
