This is just a little response to the review stating the word "Snigger" is racist.
The word Snigger is a verb and is in fact in the oxford english, the definition is as follows (taken from the oxford english dictionary):
"Definition of snigger - laugh in a half- suppressed, typically scornful way"
Please search this up if you have doubts. I would never use racial slang. Thanks for your time.
