A woman in her sexual prime between the ages of 30-39 who prefers to date younger men. The term "puma" does not apply to women before their 30s, and should never be confused with the titles "Cougar" (ages 40-49) and "Jaguar" (ages 50+).
A common idiot misspelling of "Phlegm", which is "a thick, sticky, stringy mucus produced by the respiratory tract, usually as the result of irritation, inflammation, or infection of the airways."
