Twitch Global Emote

TombRaid references the Tomb Raider series: it is styled after the Tomb Raider lettering, with an ice axe. It turned up in 2018, the year of Shadow of the Tomb Raider, which was promoted heavily on Twitch, from a visit to the Twitch E3 studio in June to a launch stream with Twitch in September. Neither Twitch nor the publisher ever mentioned the emote itself.
