Hashtags are words or terms which are used to categorize publications in social media, indexing the content and making it available for retrieval. The hashtags creation is free process, i.e, there are no rules or restrictions to create them. Otherwise, there is a convergence of the terms used to explain and semantically enrich the content. This work aims to study the use of hashtags for the crowd to describe major events. The rise and acceptance of hashtags in major events related to politics, disasters, sports and entertainment were analyzed. Although the broad diversity, we identify some language patterns in the use of hashtags created by the population. Moreover, peculiarities were analyzed in each studied event.
