'Signal' is a slang word which originated from a group of students who studied in Leicester, UK.

Can be pronounced signal, or sig-nal (a as in 'pal'), the latter used in street slang followed by a 'rude-boy' knuckle-clicking gesture, as popularised by Sacha Baron Cohen's character 'Ali G'.

The term is used as a positive response to an event which is very good, or as a response to an object which is of very good quality.

Its origins lie in the context of having a very good television reception/signal.
