Get the gruby mug.
Grubying is a term assosciated with that of malding - however, it is typically characterised by those of polish descent or those living in Poland.

Grubying is typically characterised by a strong defensiveness combined with the shut-down of the subject who is grubying, rendering them unable to continue arguing at the strength of their grubying.
If this is done online, it is typically characterised by the act of leaving a game. This is typically performed under the guise of 'needing to eat dinner' - even at irrational times.

To commence grubying, one must continue arguing until the subject (Reminder that this is perfoemed on Poles), is no longer in a good capacity to argue. This is the beginning of Grubying.
This can also be done through criticising and critiquing Polish cultural norms, such as their food or customs.
