No just more versed on the subject than you appear to be.
Stacking of the court means creating additional judge seats. Adding more judges. That's what stacking the court means. Adding more supreme Court judges in addition to how many there are now. Why don't you look it up or read a book?
Or not ...
"What does it mean to pack the courts, is it the appropriate response and would it make the courts less of a partisan battleground issue?
People often use "court packing" to describe changes to the size of the Supreme Court, but it's better understood as any effort to manipulate the Court's membership for partisan ends. A political party that's engaged in court packing will usually violate norms that govern who is appointed (e.g., only appoint jurists who respect precedent) and how the appointment process works (e.g., no appointments during a presidential election).
Seen from this perspective, the Barrett appointment is classic court packing. The president nominated a hardline conservative who appears to question major parts of U.S. constitutional law. And the Senate majority changed its procedural rules – invented to deny Merrick Garland a hearing – to ram through the nomination as people were voting."
