Meaning

Running out of mobile data — the dreaded state of having exhausted one's monthly data allowance and being throttled to unusably slow speeds.

Combining ギガ (data) with 死 (death), ギガ死 dramatically describes the moment your mobile data runs out and speeds drop to a crawl. The 'death' metaphor captures the genuine frustration of modern smartphone users who feel cut off when they cannot stream, browse, or use apps at normal speed. It is a universally relatable complaint, especially among younger users who consume large amounts of video content.

Examples

1. まだ月半ばなのにギガ死した、TikTok見すぎた。 It's only the middle of the month and I already used up all my data — I watched too much TikTok.
2. ギガ死してるから画像全然読み込まないんだけど。 I'm out of data so images won't load at all.
3. 来月からプラン上げないとまたギガ死するわ。 I need to upgrade my plan next month or I'll run out of data again.
