cmon

An informal written contraction of "come on," dropping both the apostrophe and the space so it can be typed at speed in chat, comments, and texts. It functions as an interjection: pleading ("cmon just one more game"), urging ("cmon team, push mid"), expressing disbelief at a bad call or outcome ("cmon ref"), or coaxing someone into a decision. The form mirrors how the phrase is actually pronounced in casual speech, with the schwa collapsing the two words into a single syllable, and it dominates Twitch chat, Discord, sports threads, and SMS. Despite being technically non-standard, it's so common that style guides for online writing treat it as an accepted register choice rather than a typo.
