A dad joke is a weak, corny joke, typically a pun, that a dad would tell to his children. Not a complement. None of your jokes should be labeled “dad jokes.” A typical reaction is not a laugh, but an eye-roll, or at best, a groan.
Just what are mom jeans? They are a high-wasted, roomy jeans, comfortable but unflattering, preferred by moms in the 1980s. The term became popular in 2003 from a fictitious brand featured on a TV Saturday Night Live skit which used the tagline “For this Mother’s Day, don’t give Mom that bottle of perfume. Give her something that says, ‘I’m not a woman anymore . . . I’m a mom!’” (written by Tina Fey).
It is a pejorative term, but many women prefer the roomy fit and look of mom jeans, rather than the skin-tight, low-cut styles worn by teenaged girls.
