This gem was uttered by that blonde bombshell, Lara Hayhurst Compton, and so could fit in the category entitled “blonde malaphor”. It is a mash up of “better safe than sorry” (be cautious or you may regret it) and “better late than never” (doing something late is better than not doing it). Both expressions do indicate someone doing something, albeit cautiously. “Late” and “safe” are both four letter words and sound similar, adding to the mix-up.
For your consideration – Maybe Lara has unintentionally created the new safe sex slogan. It could replace the abstinence slogan “Just say no”. A big thanks to Lara Hayhurst Compton for blurting this one and sending it in!
