A blowwy?

Okay so my SO is coming over and he's like "do you wanna take a nap" and I said" no... But I have a surprise for you" and he goes "oh?" And I go "mhmm" and a little later he says " it is a blowwy" an si haven't answered him yet
Little does he know my bestfriend is going to be in my bed and he's gonna walk in and she gonna be like " HEY BRO!!" 
Lmfao we've only been together about a month and he thinks he's getting some. Well...he's in for a surprise
