The short answer
Most pregnancy-test shorthand describes a person’s impression or testing context. Terms such as squinter and line eyes are not validated result categories. Your test’s instructions remain the reference.
Community shorthand can make an already uncertain moment harder to follow. Here is a plain-language guide to common expressions, without assuming what result you want.
Words for a faint or uncertain mark
- Squinter
- A mark someone finds difficult to see. It describes visibility, not a confirmed outcome.
- Line eyes
- The feeling that repeated looking makes it hard to trust whether a line is actually there.
- VVFL
- Very, very faint line. The letters do not establish what caused the mark.
- Evap
- Short for evaporation line, often used for a mark seen after a used test dries.
- Indent
- An informal label for a pale impression or groove at a line position.
Words for timing, products and outcomes
- DPO
- Days past ovulation; often an estimate in a forum post.
- FRER
- First Response Early Result, a specific product rather than every First Response test.
- BFP / BFN
- “Big fat positive” / “big fat negative.” These are community expressions, not instructions or medical categories.
- TTC
- Trying to conceive. It describes one context for testing, not everyone’s reason.
- Dye stealer
- An informal description of a test line appearing darker than a control line; not a clinical assessment.

Asking for a second set of eyes
If you choose to ask someone to look, provide the product name, the reading time and an untouched photo. “I saw this during the reading window, but the picture is unclear” is more informative than asking for a vote on “squinter or BFP?”
You do not need to share your desired outcome to describe a test. “I hope this is positive” and “I really hope this is negative” are both understandable feelings, but neither changes what the image can establish.
Where to go next
For the visual question, read what to check with a faint line. For an evap label, start with the timing comparison. For an app, read what 2Lines can help you review.
Use these terms to understand a conversation, not to make a medical decision from a stranger’s caption.
