Archie, good list with only a few problems:
Hate (to) is "odiar" not Idiar" It's a reflexive verb, so like gustar (to enjoy, to taste) it is used as if the thing you hate really hates you instead (de vez de). "Me odian las Colombianas/ I hate Colombianas)."
In C.R. to have an orgasm is regarse...literally, to irrigate oneself.
To turn on, a radio or Hitachi Magic Wand for instance: In C.R. they'll often use the verb "aprender," as in the command "Aprenda la radio/turn on the radio."
Culo: Literally, as$hole. The arse is the cola or more politely, tracero.
Interesting fun fact: Even though your dictionary will say the word for towel is "toalla," in C.R. it's not right. Ticos use "pan~o," because toalla in C.R.'s idiom means sanitary napkin or feminine hygiene pad.
Note that all nouns are either masculine or feminine, and adjectives must be de acuerdo (in agreement) with the noun.
Una muchacha lista/un muchacho listo A clever girl/a clever guy.
In C.R. a BJ can either be una mamada or una chupa. "Sexo oral" is perfectly acceptible also.
I'm sure I'll find a few other small things as I read the list a second and third time. Great effort, Archie! I'm sure that this will become a very useful tool.
