the epitomy of english schoolboy and appropriate as a response to anything!

"allow it" means to just leave something alone, or don't worry about it. People in West London say this quite often.

Is the shortened nickname version of Rathbone; that being a last name

Rathers is that guy who seems to be prone to being friend-zoned and also who gets hit in the head with a Volleyball. Rathers also seems prone to having his phone lost/stolen/confiscated at school. Most likely, he is an average sized human but sometimes they are hit with the ugly stick at birth and end up having a pepperoni pizza as a face.

it is a cameo of infinitude that many fail to comprehend with their increasingly miniscule sphere of thought in which other banal rungs of ideas and thoughts are seated before the graces of the power that is the vastness of reason and all that is good in the world (including spice and everything nice, but the stuff that makes up boys (which i do not choose to explicate in this space for its pure vulgarity in the face of "rather")may be included if one takes the bokonist view of "as it ought to have been")

More readily or willingly.
