Translation: stranger, foreigner [noun, m]
The word tujec comes from an adjective tuj, meaning foreign, unknown, unfamiliar. Nowadays it is commonly encountered in media, given a global working market and migration patterns. Note that a female stranger is tujka; tujka is used to describe a word, that clearly originates in another language and has been adopted (and typically slightly adapted) to Slovenian (example: alergija for allergy).
