# My Face When (MFW)
My Face When (MFW), also written as That Face When (TFW), started as an opening line for 4chan reply posts in late 2009 before spreading to Reddit, Tumblr, and gaming forums. The greentext-style tag pairs a described situation with a reaction face image, and it laid the groundwork for the wider vocabulary of feelings-based caption memes.
## Origin
The earliest archived >mfw post traces to a 4chan /mu/ music board thread titled 'Syd', dated November 29, 2009[3]. The tag spread across other 4chan boards through late 2009 and into 2010, riding the general convention of using > (greentext) as a post prefix. Most early examples only survived through third-party imageboard archives, since 4chan does not keep threads long-term.
- **Platform:** 4chan (originated) / Reddit, Tumblr (viral spread)
- **Creator:** Unknown
- **Date:** 2009
## Overview
The format works by prefacing a post with >mfw and either describing a situation in text or attaching a reaction face image that stands in for the poster's expression[3]. Threads on 4chan often collect dozens of >mfw replies to a shared prompt, turning the board into a running feelings check-in where each user picks a face to represent their reaction[1].
Common variations include >tfw (that face when), used when the reaction belongs to someone else or a hypothetical person, and greentext stories that close with a >mfw punchline[2]. Reaction faces paired with the tag range from MS Paint drawings like Feels Guy to celebrity screencaps and cropped cartoon panels, and the tone shifts from smug to horrified to deadpan depending on which face gets picked.
A related snowclone, 'My Face When X Calls Y Z', came out of 4chan's /v/ board and pokes fun at word-usage differences across English-speaking countries, usually attached to a shocked or smug reaction image[3].
## How It Spread
Urban Dictionary added an entry for >mfw on June 12, 2010, describing it as shorthand for the reaction face a poster would make[2]. Around the same period, someone registered MyFaceWhen.com in March 2010 as a reaction-face collection site[1], and a separate database launched at MyFaceWhen.net in March 2011 as a reaction-image reference[4].
By April 2011 the tag reached Reddit, where the r/mfw subreddit collected image posts using the format[5]. Tumblr users adopted the mfw and tfw tags for their own reblog reaction culture, giving the shorthand a second home outside imageboards[6]. Forums like Terraria Online, Bungie, and Xbox360 Achievements also ran 'My Face When…' threads as icebreaker games[3].
## How to Use
A typical MFW post opens with >mfw followed by either a described situation or a reaction face image showing the poster's imagined expression[1]. The related >tfw tag is used when the reaction belongs to someone else or a hypothetical person[2]. Common convention is to keep the description short and let the paired face do the work, though longer greentext stories often close with a >mfw punchline image.
