Used by Eegra in their valentines day comic, where Bowser handed Peach a card with this phrase, and subsequently believes it is a sweet love message. Or something. Whatever the case, it's an exclamation yelled at a loved one that expresses ones awkwardness in a social or romantic situation.
"Happy valentines day! I will tear you a second cunt with my thorny cock!"
