Hi Almuhjjar, and welcome to Thunders place!
UPS could be United Parcel Service. Those are the guys in the brown trucks that deliver packages. Sorry if some of what you read here is hard to understand, we do try and use only international English.
Native English speakers:
This is why we try and avoid chat speak, slang, and poor spelling! Plenty of the members are from all over the world and are using a translation program on words that they don’t understand. One of the things that makes Thunders so cool is that we have members from all over. We like it that way and intend to keep it that way. If you still don’t understand that chat speak and bad spelling can make you an Ex-member go read the forum guidlines.
