The contracted form of the phrase "come on". Eliminating the space between the two words, the letter "e" and substituting the "o" in "come" with an apostrophe.

Generally used to encourage one to hurry up or follow in one's path.

"allow it" means to just leave something alone, or don't worry about it. People in West London say this quite often.

A horrible way to try and convince someone to go along with something or do something.
