The line is in French and translates literally to I do not eat seeds, which is part of why it travels well even outside French-speaking audiences once subtitled. Clips of short foreign-language refusals became popular on soundboards and in edited videos because the meaning can be understood from tone alone. This one is shared mainly as a reaction sound, posted in comments, remixes and short videos whenever someone wants to reject an offer, a trend or a suggestion without explaining themselves any further than that.
