ST:NG 

Star Trek: the Next Generation - the second tv series in the long-running science fiction franchise

usually pronouneced as "S T N G", as separate letters with no reference to the colon, even though it is _always_ written with the colon

also called simply "Next Generation" by the geekazoids

sometimes also written ST:tNG

"He is such a geek, when he says ST:NG you can hear the fucking colon in it, I swear"
