As long as it's used in a mature way and not blatantly vulgar. A splash of tongue in cheek goes a long way while inappropriate overuse reduces impact. Like CAPS. Plus try to stick to relevant topics in threads, like Tea.On that note, I prefer Jasmine, Lotus, Earl Grey w/ Bergamot, and Darjeeling.
Speaking of redundancy, it's a pet peeve of mine when people say "chai tea." Chai is tea. Chai means tea.
