Whaqqn is a neologism whose origins lie in the slang definition of the word "Whacking" which is "To Kill"

However the word has evolved and predominantly characterises the deft manner in which a player or team faces their opponent. In this way they are said to be 'whaqqn' when their actions are skilfully executed.

In the gaming world it is often thought that the word describes the way in which a cheater (or hacker) attains success but this is inaccurate - although true whaqqn will appear effortless it is achieved honourably.
Adjective:

# Beware, the whaqqn ones.
# Despite disruption, the professional is whaqqn.
