Depends if you think they are actually British, or are just living through an invented persona, where they choose an Avatar that resembles a drug dealer character from a teenager's video game. Tells you something about their lack of confidence and self worth, so they invent the character they want to be; he chose the character of Trevor Philips from GTA V. Trevor, from GTA V, is portrayed as volatile, aggressive, anarchic, obscene, unpredictable, contemptuous of social conventions, and intensely suspicious of hypocrisy. He also has a strong streak of dark humour and enjoys deliberately making other people uncomfortable. SO "JonnyF" routinely: deliberately antagonises other posters, use sarcasm rather than straightforward argument, makes deliberately outrageous statements, ridicules people they regard as sanctimonious, enjoys watching arguments develop, attacks perceived hypocrisy on both sides, and seem more interested in defeating or humiliating an opponent than persuading them This suggests JonnyF is someone who derives social reward from confrontation itself. But JonnyF has deliberately constructed a Trevor Phillips persona for their online identity, rather than simply using a character they like, the avatar can be understood as a kind of idealised or liberated alter ego: "This is who I get to be when the constraints of ordinary social life are removed.". So a desire to be unconstrained (in his normal life he feels constrained), a repressed aggression, as a compensation for a lack of aggression offline, a fantasy of dominance. Offline, he is naturally cautious, socially constrained, he worries abut being judged and normally avoids confrontation.
