1) A man whose
wife is sleeping
men, he may or may not have knowledge of it but when
calling someone a cuckold it usually insinuates
that he does.
2) In porn
, it usually
has to do with a white man with a small penis watching a black man with a big penis fucking a woman (almost never actually his wife, but portrayed as such for the porn
flick). Many homosexuals who are too scared to admit they're gay watch it just because it has a big dick; they couldn't care less about the woman.
