Get the bruh-sismug. Some retarded bullshit "phrase" used by the idiots that populate the Random Nonsense forum on the Day of Defeat official website. It makes absolutely no sense and is beyond retarded. Using 'si' instead of 'is', is no longer funny. It became unfunny after JeffK's popularity died out 3 years ago. Please stop emulating him. It's really, really dumb. Thanks.
