chip butty? yeah sure that’s basically my day-to-day diet anyways.
Doctor Who? yeah thanks to my dad I’ve seen and committed to memory more of that series than I have any American sport - including shit like the War Doctor.
miserable weather? actually my favorite kind.
tea? I’m breaking from the pack here and asking for iced black tea but sure.
Channel 4 shows? This post was literally prompted by me finishing my weeks long Taskmaster binge after being recommended an episode on Youtube; please help me!!! 
Channel 4 is the based channel and I don’t think that should count towards your bad Britishness quota. If you watch BBC, ITV or 5 then yeah, it counts towards your bad quota.
Iced black tea will push up your US quota.
Chip butty, miserable weather and corny British Sci-Fi for sure pushes it way up, but I would say in a good way. I will die in the hill fighting the notion that British food is bad. And before you come at me, I’m the most worldly food eater you will ever meet. I appreciate everyone’s cuisine, except the US fake food because fuck that.
Bad ways to push it up are loving the royal family, watching premier League football, and thinking Churchill and the British empire were good things.
