= A very long forward pass in American football, typically made in desperation, with an exceptionally small chance of achieving a completion. Due to the difficulty of a completion with this pass, it makes reference to the Catholic "Hail Mary" prayer for strength and help.

https://en.wikipedia.org/wiki/Sulfur_dioxide
Chemical compound with the formula SO2 (small 2 next to O).

Sulfur dioxide is the product of the burning of sulfur or of burning materials that contain sulfur.

It is a toxic gas responsible for the odor of burnt matches.

The roasting of sulfide ores such as pyrite, sphalerite, and cinnabar (mercury sulfide) also releases SO2 (small 2 next to O).

As a fumigant
In the beginning of the 20th century, sulfur dioxide was used in Buenos Aires as a fumigant to kill rats that carried the Yersinia pestis bacterium, which causes bubonic plague.

Ingestion
Symptoms of sensitivity to sulfiting agents, including sulfur dioxide, manifest as potentially life-threatening trouble breathing within minutes of ingestion.[43] Sulphites may also cause symptoms in non-asthmatic individuals, namely dermatitis, urticaria, flushing, hypotension, abdominal pain and diarrhea, and even life-threatening anaphylaxis.[44]

Inhalation
Incidental exposure to sulfur dioxide is routine, e.g. the smoke from matches, coal, and sulfur-containing fuels like bunker fuel. Relative to other chemicals, it is only mildly toxic and requires high concentrations to be actively hazardous.[45] However, its ubiquity makes it a major air pollutant with significant impacts on human health.
