Glad to see another study blog! 
lol 
Don’t take it from me, but some time back I made a thread about stuff like that…
Kuso! - What NOT to say in Japanese - swearing, sex, and general rudness
Now, lv 48 I have finally encountered a swear word kanji: livestock: 畜 part of “damn”
畜生 【ちくしょう】 (int,n) beast, brute, damn, (P)
I hope learning this early on will serve you well! XD
