Sarcastic compariSON of a virile
stud's chest-pounding celebration at having successfully "scored" wif a hot chick, but then having to deal wif da "pitter-patter of little feet" if said glorious union produces a "tiny-male result" --- i.e., a "
stud junior".
In
da alternate "hill-ascending duo" poem, it's stated
dat "Silly Jill forgot her pill"; I guess dat she forgot a condom, as well, since
da "I da MAN!" = "Little Man" equation certainly applied in their case.
