sasinack means: An English term that describes the English. A derogative term that is used in Scotland to describe the English. There is likely a connection between the words traitor or assasin going back to when the English were in control of the Scotts. This word is mostly used to refer to the English by some Scottish citizens. They may attempt to say that they’re sassinacks when they come in contact with someone from England. The majority of English cannot comprehend the Scots so using words like “sassinack” in conversation can increase the bewilderment. (in Community Dictionary, added by Borja Jiménez)
