A derivative from the italian word "squillo" meaning "ring", "beep" (also a euphemism for "prostitute"). It refers to a short ring on a mobile phone that does not require an answer to the call. It's used as a quick and cheap way no notify somebody e.g. that you're arrived in a place. Teenagers also use it a lot as a way to say "I'm thinking about you".
- I'm going to meet you at the cafe later
- OK, then give me a ring when you arrive
- Man I can't, my mobile's out of credit
- Well, then just give me a squeal
