teh probably annoys me the most...
Yet I am not uptight about use of grammar and spelling, unless standard English is essential. So on a forum like this I ignore typos and slipshod grammar quite easily. Heck, John Calibre can atest to some of the whoppers I can make on my phone (let alone on a PC).
pwned or owned... I find both annoying. Owned is a ridiculous expression to me, so to deliberately misspell it... I guess for irony pwned would be marginally less annoying than owned.
