Idiom
Etymology:
Of Native American origin it describes the inability of a person to successfully walk through tall grass. Before colonization the great plains of North American were covered with large sections of tall grasses. Instead of going around acres of tall grass, people could walk straight through them.
The implication is that a capable adult is both tall enough to see above shoulder height tall grass and wise enough to navigate and form a path through tall grass that is above their head. Children and people that are not intelligent will get lost in the tall grass and need help to get out or even die.
Usually applied to a person, but could apply to a thing.
Similar to: If you can't handle the heat get out of the kitchen, shape up or ship out
1: transitive, present tense
a: Describing a person that cannot handle the situation they are in.
b: Describing a person that is not intelligent enough to figure out something that others easily can.
2: rhetorical question
Implying that the person being asked is not keeping up with the group or not able to handle the task they were given.
