Language is constantly changing. "Homosexual" refers to sexual activity between two people of the same sex, so -- strictly speaking -- saying "That person is a homosexual" would be like looking at a firefighter and saying, "That person is a fire." In general usage, "a homosexual" may refer to a male or a female. Until the 1960's, the word "gay" was used to refer to a homosexual person of either sex. Now, "gay" refers almost always to a gay male; homosexual females are "lesbians." At this time in the US, the preferred phrase (assuming you are referring to homosexual people in general) is "gay and lesbian" or "lesbian and gay." "Homosexual" is used only as an adjective to describe particular sexual acts. Once again, though, language is constantly changing.

The word homosexual has a clinical feel to it, and they insist they are born that way and have nothing wrong with them. Now, the word gay can be slang for the word stupid. A person may call a boring movie gay. That is a somewhat offensive usage, since it sort of lumps gay people in with things that are stupid, shoddy, inferior, etc.

No. "giggle" in Spanish is "risilla" or "risita." "Gay", in reference to a homosexual individual, is "gay" in Spanish. Sort of a Spanglishism.
