drum out
Eject in disgrace
To drum out is to expel someone from an organization, especially a military one, in disgrace.
The phrase evokes the old practice of escorting dismissed soldiers off base to the beat of drums.
It now applies more broadly: He was drummed out of the party after the scandal.
The image suggests public humiliation accompanying the removal.
