A tasty polynesian treat; consisting of a generous serving of South Pacific Asian Meat sandwiched between 2 or more intensely euphoric women.
The spam sandwich is said to be a powerful aphrodisiac.

When you want to invite friends somewhere (like a gig) and you send them a normal txt/email, followed by your spam advertising the gig, followed by another normal txt/email.

1st Message: Hey man, long time, how you been? How's things?

2nd Message: Oh btw, I have a gig coming up, do you wanna come? Here are the details aka SPAM!

3rd Message: How's your dog?

Note: It is important to note that you need to wait for them to reply to your message before you send the next layer of the sandwich.
Oh shoot, I just copped another spam sandwich from Mikey, I should really just go to one of his gigs.
