Caking is the verb...when one cakes, they are caking.
When you get a text: "Baby, I miss you" and you smile and can't stop cheesing.
Girlfriend: "Oh Bobby is so sweet, he got me flowers and chocolates and a ring for our anniversary. Omg I love him so much...I can't live without him...he always has me smiling...he told me he loves me."
Friend: "You guys are such cakes!"
When you're at a party and you spend the whole night texting that special someone ;)
